I'm trying to find RPM of a dc motor using PIC24F microcontroller. I've 200 RPM DC motor and IR sensor. I'm counting the pulse input from IR sensor when black material which attached with DC motor shaft contact with IR sensor. I'm printing pulse count for every 60 seconds using PIC timer...
Hello,
I'm starting with this new project of mine, I am just new to this thing and I hope I'll make it work. I will be using a Pulse sensor https://www.sparkfun.com/products/11574
