I purchased a sparkfun Arduino pro mini start kit and a proximity sensor #sen-15177 to do a project where when an object gets close a servo turns. got it to work on a Arduino uno, and moved to the pro-mini. everything works when using the sparkfun fdti module to connect to computer through the usb. when I power with 4 AA’s through the Raw pin, it will not turn the servo. I think the problem is the servo not getting enough current. Can I use a servo connected to vcc on the pro-mini?
Hi krswinney.
That’s a good theory!
Yes, you can power the servo directly from the battery. Just connect the servo’s power lead to RAW along with the batteries positive lead.
Yes that works!~ thanksTS-Chris:
