Simplified RPM induction sensor

Hi. I am Mihai from Romania.

This is a simplified version of a induction RPM sensor.

This is designed to be used along with an Arduino of any sort. 

You have to use a solid copper wire and twist it 9 times around the lead to the spark plug then connect it to the COIL+ terminal on the board.

The circuit uses the inducted current to switch on and off a transistor which in turn sends a signal to the Arduino used to calculate RPM.

Thank you PCBWay for making this possible. Thanks to the sponsorship program I can build my PCBs easily and I can promote your services. PCBWay manufacturing cost is very low for the average consumer. THANK YOU!
