Making a tachometer with arduino has never been so easy. I am not only going to show how you can make your own, but also will mention the pros and cons of a few types of RPM sensors, mainly the IR proximity sensor and the hall effect sensor.

Example codes:
– Simple tachometer (Serial): https://drive.google.com/open?id=1fF-b-D2hYyrRiSvu4FH45FCHrIeO1kYh
– Tachometer with 0.96” OLED display: https://drive.google.com/open?id=1oll_jWIdnyjJan-R98_XlnNrz5qeWjuJ
– Tachometer with Nextion display: https://drive.google.com/open?id=1KU-hD0ka0OCy0LU9op8_W5vsdTbC4R5B

Nextion display tachometer gauge (3.5” enhanced): https://drive.google.com/open?id=1HcQ8izH8SXbORlsU7_g15CTJrmq_65al
