About this project

This project is one I have been wanting to do forever. I found a car tachometer for about 20$ on Amazon and then purchased components elsewhere. So all in all about 28$ were spent. With this project it will allow you to utilize your automotive tachometer to simulate r.p.m's on your tachometer. Also any tachometer will work and any arduino can be used for this project.

Code

The codeArduino
int tachPin = 9;
int tachDelay = 10000;

void setup() {
  pinMode(tachPin, OUTPUT);
  tone(tachPin, 33);
  delay(2000);
  tone(tachPin, 388);
  delay(2000);
  tone(tachPin, 33);
  delay(1000);
  delay(2000);
  tone(tachPin, 388);
  delay(1000);
  tone(tachPin, 200);
  delay(1000);
  tone(tachPin, 300);
  delay(1000);
  tone(tachPin, 166);
  delay(1000);
  tone(tachPin, 300);
  delay(1000);
  tone(tachPin, 233);
  delay(1000);
  tone(tachPin, 178);
  delay(1000);
  tone(tachPin, 300);
  delay(500);
  tone(tachPin, 33);

}

void loop() {
  //tone(tachPin, 33); // 1000 RPM
  //delay(tachDelay);
  //tone(tachPin, 66); // 2000 RPM
  //delay(tachDelay);
  //tone(tachPin, 100); // 3000 RPM
  //delay(tachDelay);
  //tone(tachPin, 133); // 4000 RPM
  //delay(tachDelay);
  //tone(tachPin, 166); // 5000 RPM
  //delay(tachDelay);
  //tone(tachPin, 200); // 6000 RPM
  //delay(tachDelay);
  //tone(tachPin, 233); // 7000 RPM
  //delay(tachDelay);
  //tone(tachPin, 266); // 8000 RPM
  //delay(tachDelay);
  //tone(tachPin, 300); // 9000 RPM
  //delay(tachDelay);
  //tone(tachPin, 388); // 10000 RPM
  //delay(tachDelay);
