My custom gauges for my '65 Mustang (still waiting on one to show up). .96" OLED displays (I2C) run off an Arduino Mega 2560 and talking to my AEM Infinity over CANbus. This is boot sequence and then live ECU data. The flicker at the beginning is me resetting the Arduino. Data is boring because the ECU is sitting on my couch and my couch is not turbocharged (yet).
