Now there is plenty of information out there on PICs, servos, steppers, etc. My problem is that my project is targeted at teaching linux programming in developing countries- and thus our budget is like zero
So i want to make it as cheap as possible. Any ideas? Thanx.
Ok i've done some research. I have to admit that i am not experienced in engineering, so please explain stuff you think is simple
Need to turn a small 3-7 volt motor on and off.
It seems that the cheapest way to turn something on and off by a signal from pc is to use a relay. I don't need feedback, so it's gonna be centronics.
If you have a link to say "a project to turn a led on and off " that is simple, that would be the answer to my question
Use a relay? It's probably easier than using servos or steppers and controllers and all, right?
1) which relay do i choose? hopefully under $2, found in old vcrs or toasters
2) how do i connect it- which pins of the LPT?
3) which signals to send /will be using c or perl/
Thank you for your time.
