Problem controlling motor/Arduino from Sparkfun Kit
Posted: Thu Dec 29, 2011 4:06 pm
My 11-year old son and I are LOVING the Sparkfun Inventor's Kit; we bought two so we can work side by side (new kits, shipped a week ago). We're working on CIRC-03 (Spin Motor Spin) but have hit a wall. Code is exactly as listed in manual and verifies fine. Wiring seems correct as well - and as mentioned we're working in duplicate. Verified that transistor is P2N2222A as spec'd. Verified resistor is 10k using multimeter. Tried diode both ways to be sure. Tried resetting board and re-uploading. Nothing. Motor runs fine when directly connected to power so that's not it. Any known problems with this CIRC? Many thanks in advance for your help!
