hi guys
i got a wiper motor which goes with 55rpm . i need to drive this with 20 rpm. and i need to stpo after a cycle.
can i make it with arduino? i will going to use a momentery contact switch or something that you will advise.
when i push the button, the motor should turn 360 degree with 20 rpm and it should stop. the button will be pushed nearly 20 times in a day.
i am planning to buy this arduino.
can i make it with arduino?
With JUST an Arduino? No. The Arduino alone can not drive a wiper motor.
The Arduino with suitable motor driver (shield) can be used.

Stopping at exactly 360 degrees will be a real challenge. Without position feedback, like a servo has, you'll just be guessing how long to drive the motor.
an arduino and a motor driver also. it will turn 360 degree and stop. is it so diffucult?

Get in your car. Drive to a big open space. Stop. Get out. Put some cones out to define a 90 degree turn starting some distance in front of your car. Put some cones to define a stopping place, some distance after the turn.
Get back in the car. Put a blindfold on. Drive the car the proper distance. Turn the steering wheel to make the turn. Turn it back, to end the turn. Stop after driving the proper distance.
Get out. Are you anywhere near where you expected? How many cones did you kill in the process?
Feedback is absolutely essential. Without it, you are just guessing. Yes, it IS difficult.
