This is a repository for one of my personal hobby projects to design and build a car heads up display (HUD). This HUD displays car speed (in mph) and RPM in real-time to the driver. The device itself includes the following:
- 1x ELM327 bluetooth OBD2 scanner
- 1x Arduino Teensy 3.X
- 1x Arduino ESP32
- 2x 7-segment LED displays
- 1x 10-segment LED bar display
- 4x small PCB standoffs
- 35x 75 Ohm resistors
- 1x screw terminal
- 1x SSD1331 OLED display
- 1x plexiglass sheet
- 1x winshield reflective film
- 3D printed housing
