currently I am struggeling with the electronics in my following project. I hope you can help me. Thanks for any advices!
I would like to control a bunch of computer fans (5V or 12V) by using an Arduino UNO (+ external 12V power supply) and vvvv with the StandardFirmata. But I am struggeling with the electronics.
There is already a working prototype with 4x 5V Fans (each 2 wired), but I can’t manage them to be controlled with vvvv. The fans start to rotate but I don’t know how to control them.
- Do you have an example for a working, easy circuit? This would be awesome!
- Shall I use 12V fans (3 wired) or 5V fans (2 wired)?
- Which transistors, resistors are best for this case?
Thanks a lot for any help!
