Hey all. I’m wanting to power my UNO from a 12v DC system. I purchased “BaiFM Buck Converter LM2596” to power the Arduino.
Everywhere I’ve read says a different story. Some say the vin can handle 12v. Some say no more than 9. Others say only 5.5.
I adjusted the buck converter down to 5.5 and it wouldn’t power on. Since a lot of people say either 12v or 9v… I decided to adjust my voltage to 8.5 to be safe. I hooked the + into the VIN and - to ground.
After turning one of my unos into a smoke machine, I’m assuming my “to be safe” voltage wasn’t safe after all.
Can someone tell me how to hook this darn thing up? or is there a diagram on how to power the Arduino with vin? I thought simply + into vin and - into ground was the way to do it.
