I&#8217;ve been searching for a wider colour IPS display and found one that will do (for now :-). Ideally, I&#8217;d like to fill the full area below in order to properly display the seatbeat and airbag warnings as well as status messages for the rear LEDs.  I&#8217;m using a <a href=\"https:\/\/www.buydisplay.com\/1-9-inch-ips-tft-lcd-display-module-170x320-for-arduino-raspberry-pi\" title=\"BuyDisplay \" target=\"_blank\" rel=\"noreferrer noopener\">BuyDisplay <\/a>1.9 IPS display (320&#215;170) mated to an ESP32 DEVKIT V1.  As I had some challenges getting the display to work with the ESP using TFT_eSPI, I&#8217;ll probably do a video for that another time.  Watch below to see the evolution of the build.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Mazda MX-5 Miata Rear LED Light Strip Controller gets an updated colour IPS Display\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/s7M-LtdlpY8?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p><strong>Feb 2022  Phase III:<\/strong> In my search for a better colour screen I swapped the black\/white OLED for a colour IPS screen\/controller using the TTGO T-Display ESP32 controller.  However, this was a short-lived upgrade as it was not wide enough (per above), so I never made this permanent.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Miata LED Strip Controller Update Teaser\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/ZjhRD85_R-4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<p><\/p>\n\n\n\n<p class=\"has-text-align-center\" style=\"font-size:29px\"><strong><span style=\"text-decoration: underline;\">Phase II Build<\/span><\/strong><\/p>\n\n\n\n<p>If you are looking to build this project and don&#8217;t care much for the console controller, check out the <a href=\"http:\/\/www.plastibots.com\/index.php\/2021\/05\/10\/mazda-mx-5-miata-dynamic-rear-led-bar\/\" target=\"_blank\" rel=\"noreferrer noopener\">Phase I build<\/a> which focuses on the rear controller and LED strip. The below instructions are specific to using the black &amp; white OLED and 2 controllers. <\/p>\n\n\n\n<p>Backstory:  Wanting to have more control of the Miata&#8217;s rear LED strip sequences and features (see my <a href=\"http:\/\/www.plastibots.com\/index.php\/2021\/05\/10\/mazda-mx-5-miata-dynamic-rear-led-bar\/\" target=\"_blank\" rel=\"noreferrer noopener\">Phase I build<\/a>), the next step was to build a controller into the center console unit that allows me to control them and also display state and status info.   As I didn&#8217;t want to run wires through the car, the Master controller communicate wirelessly to the Slave unit.  The details documented here builds on Phase I by adding the Master Control unit, and updating the Slave unit hardware to a NodeMCU ESP8266, and of course code updates for both as well.   <\/p>\n\n\n\n<p>Check out the video below for a demo of the features, then read on below for build details.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Phase II Complete: Mazda MX-5 Miata Rear LED Light Strip - Controller \/ Display\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/wT4vkbM3ZXI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p><strong>How it Works:<\/strong><\/p>\n\n\n\n<p>Both Master and Slave units use NodeMCU Mini ESP8266 MCUs and are setup to communicate to each other using Espressif&#8217;s <a href=\"https:\/\/www.espressif.com\/en\/products\/software\/esp-now\/overview\" target=\"_blank\" rel=\"noreferrer noopener\">ESP-NOW<\/a> protocol.  This saved the mess of having to run wiring through the car. The Master consists of the controller, a display, button and a few photoresistors. All of which are mounted into the front console unit. The Slave has the same MCU and an <a href=\"https:\/\/www.adafruit.com\/product\/3635\" title=\"https:\/\/www.adafruit.com\/product\/3635\" target=\"_blank\" rel=\"noreferrer noopener\">Adafruit NeoPixel LED strip<\/a> with some other bits to monitor the brake signal.   The Master unit allows scrolling through a number of different light sequences by way of the button.  Short presses scroll the modes, a long-press initiates the selected mode.  <\/p>\n\n\n\n<p>As the OLED covers up LEDs on the main console PCB board and status LEDs, I used a few photoresistors to &#8220;watch&#8221; both the Seatbelt and Airbag warning LEDs, and when they turned on, the OLED displays the relevant icon graphic.  <em>Yes, I&#8217;m aware of my blackout decal goof, but it can&#8217;t be seen at driving height angle<\/em> \ud83d\ude09  <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a

component testing and some early ideas before the final build:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9

little simpler, this consists of the NodeMCU Mini ESP8266, the OLED, and the photoresistors. For the OLED, I have to throw a &#8216;facepalm&#8217; out there as I didn&#8217;t document the SCL\/SDA pins &#8211; which also aren&#8217;t called out in the code (don&#8217;t need to).  So, I basically forgot to note it after I hooked it all up and threw it in the car. I&#8217;ll update one day if I ever have to pull it out, but try using a combo of D5\/D4 between the two to see which will work. Could also be D7\/8 but D6 was not used. Sorry about that&#8230;  For the sensing of the Seatbelt\/Airbag alerts, I went a different route with the photoresistors due to there only being one Analog pin on this MCU.  I&#8217;m using a multiplexing approach in the code. Basically each photoresistor is connected to a Digital pin which briefly powers up in alternating sequence, then through the resistor\/diode combo the output is read via A0.  The code does all this and reads the output of each effectively allowing 2 sensors on 1 (analog) pin.  If you are using an MCU with &gt; 1 Analog port, you can just break them out and read separately (also won&#8217;t need the diodes).<\/p>\n\n\n\n<p>As for powering the master unit.  I want to be able to upload code changes in the future.  To do this, a USB cable is needed.  Since USB also can provide power, and in the case of the master not much is needed, I just hacked up a USB cable in 2 parts.  One cable is used to take 12V from the car Accessory fuse and drop it to 5V. The end of that cable is a USB female connector. Then I plug a standard USB cable from there into the NodeMCU. When I need to do code updates, I just unplug the USB cable, and plug into my tablet to update.  The picture below shows the unit from fuse panel to USB female plug.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"788\" src=\"http:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251-1024x788.png\" alt=\"\" class=\"wp-image-7049\" srcset=\"https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251-1024x788.png 1024w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251-300x231.png 300w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251-768x591.png 768w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251-1536x1181.png 1536w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/09\/IMG_5251.png 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"http:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"http:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb-1024x583.png\" alt=\"\" class=\"wp-image-7061\" srcset=\"https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb-1024x583.png 1024w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb-300x171.png 300w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb-768x438.png 768w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb-1536x875.png 1536w, https:\/\/www.plastibots.com\/wordpress\/wp-content\/uploads\/2021\/10\/Mazda-MX-5-Miata-Rear-LED-Light-Strip-MASTER-Controller-Display_bb.png 1755w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p>Slave Unit:  The below schematic was updated from the <a href=\"http:\/\/www.plastibots.com\/index.php\/2021\/05\/10\/mazda-mx-5-miata-dynamic-rear-led-bar\/\" title=\"http:\/\/www.plastibots.com\/index.php\/2021\/05\/10\/mazda-mx-5-miata-dynamic-rear-led-bar\/\" target=\"_blank\" rel=\"noreferrer noopener\">Phase I build<\/a> to include the NodeMCU Mini ESP8266 and remove the manual mode button.

One thing that bugs me is the visibility of individual LED &#8220;pixels&#8221; when looking at the back of the car.  I&#8217;m going to take a stab at using the below LED light channel.  It has an semi-opaque side where the LEDs face which blends the light from each pixel, which makes the LEDs flow from one to another.
