We have made a construction for a mechatronic course. The construction is like this:



Our problem is simply the code for the 16f917 mcu, which we are gonna program with pic code.

We need to convert the analog signal from the electric motor (tachometer), to digital signal. The axel will be powered by a drilling machine. The digital output should be computed and the solenoid should react to that input.

Like if the digital signal reads zero very quickly (quick deacceleration), the solenoid should brake with a pulse to prevent the "wheel" from blocking. And if the axel doesnt spin and you brake, the solenoid shouldnt brake with a pulse, but just normal.


We have completly newbs at this, and understand absolutely nothing, so plz we would appreciate language that everyone understands

If someone knows of a website or something else, plz link to it :P

Thx in advance
