video Digital speedometer, tachometer & engine temperature display
This project is so complex :)
1- LED tachometer (right one)
2- LED speedometer (left one)
3- Digital (seven segment) display for Speed, RPM & engine temerature. I'm switching between the 3 inputs using one of the car's original rotary switches.
