Sorry, wrong assumption- using 2.60
Quick question and slightly off topic, but related to this project... I'm using an H-bridge to control the motor as I need it to be bi-directional. I've been experimenting with some NPN and PNP transistors that I had in my hobby box, BC639 and BC640 and have had a small low current motor running from the PIC. However the actual motor I will be using is a 540 type with a 6:1 gearing. Even though it will be running from a 3v supply (separate to the 5v pic supply) my guess is that the current might be too high for the BC639 / 640 transistors. Can anyone advise if using these transistors would be OK for such a motor, or should I use something like the TIP220 transistors ??
