RPM SIGNAL GENERATOR

This generates a square wave using the Arduino TONE command. The output is currently confiqured to Digital Pin #5. Wire this pin directly to the input of your SHIFT LIGHT TACH SIGNAL IN No Transistor is needed.

/********** CONFIGURATION **********/

/* INSTRUCTIONS Set your RPM lowpoint (RPM_MIN) to the lowest point, do not go lower than 2000 RPM. Set your RPM highpoint (RPM_MAX) to the redline of your vehicle. The Accel_Rate variable is used for the speed at which the generator sweeps through the RPM range. A higher Accel_Rate variable will result in a slower speed. Try to keep this between (10 - 50).

Pulses per rev varies mainly by engine cylinders (4, 6, 8, etc), but may also be influenced by manufacturer, 'wasted spark' and other variables. Here's a typical chart to get you started, but to simulate your exact conditions you'll need to research. 4 cylinder = 2 pulses 6 cylinder = 3 pulses 8 cylinder = 4 pulses */
