I'm trying to activate a 12v solenoid using the Arduino. My project also utilizes a 12v stepper motor, and I'm using a ULN2003A IC to drive that. I figured I could connect the solenoid to the ULN2003A in the same way as I connected the stepper motor, but the IC gets burning hot.
Datasheet for the IC is here: SGS Thomson Microelectronics mXtyyvx datasheet pdf
I don't know the details on the solenoid, only that it's 12 volts. Maybe it pulls more than 500mA from the ULN2003A? I don't have much experience. I desperately need help though as this is for a school project due soon.
Thanks in advance,
Scott
