Decrease voltage for rotisserie
Good day
My electronic knowledge is limited,:biggrin:!
I want to build a rotisserie and have a 12v motor vehicle wiper motor, that I put on 3 AA rechargeable batteries in parallel to get 1.2v so that it rotate slower, but it is still a little bit too fast. Is there any way to decrease the voltage / speed? I have tried with a resister, but it does not rotate at all. I assume it is because the current is also lower.
Re: Decrease voltage for rotisserie
You can search Ebay for "PWM motor control". Motors draw a lot of current so your
batteries may not last very long. You could build your own pwm controller, but it is hard to
beat the ebay prices when you consider time and materials.
Here is one example

Thank you very very much!!!!

Can I do the same using a PIC16F877 Circuit?

Koossa, Why use such a large processor for a simple task? This is for an 8 pin PIC. Here is a quick program I wrote for a pwm controlled rotisserie for popping the bottoms off bottles with a heated wire. Enjoy....

Thank you Dave, the code looks a bit difficult for me, but I am a bit rusted, hehe.
I will give it a go, thanks!!
