Hello,
A couple questions for yall, would highly appreciate any guidance you have to offer.
Basically, I'm trying to power 2 (1A/12V) Solenoids, 1 (1.7A/phase/3V) Stepper, and 2 Flexiforce resistors with an Uno, Motorshield R3, and Big EasyDriver.
My thing is that it seems like Arduino browns out and overheats whenever I have my stuff connected up. I haven't tried using any transistors/resistors yet because I'm unsure about them at this point (except with the FlexiForce because I found an easy to understand sketch that helped with that).
So far I have a 12V 5A power supply hooked into the Vin/GRD screw terminals on the motor shield. I have (right now) one solenoid plugged into the A terminal. When I turn on the solenoid, the Arduino starts heating up really fast. How do I fix this? I could speculate as to why this is happening but to be honest I really just don't know.
Also, I plan on driving the Stepper with the Big Easy Driver so how should I connect my power supply to both the Arduino Motor Shield and the Big EasyDriver?
Thanks all.
Should this circuit be able to work as is without over heating?
