I have a bit of a dilemma and wanted to see if anyone can help out, I am using an arduino nano to control a npn transistor that is used as a switch to drive a load that needs about 200mA of current. The whole thing is powered externally, but both the arduino and the load are connected to the same power source. Now here's the issue. I am afraid that if the power supply is not turned on and I am programming the arduino will attempt to drive my 200 mA load and will die heroically in the attempt. Is this what I can expect to happen or am I overlooking something? Any ideas how to solve my issue?
Thx in advance!
