So I had a idea to make a select fire stampede. My thoughts were to perhaps do it with an ardunio
So I was going to have a circuit where the negative wire of my 3s lipo is connected to the negative terminal of the motor, and the positive rail is going from my lipo would be connected to the collector of a transistor, with the ardunio hooked up to the base and the motor connected to the emitter.
So when the trigger switch is activated, then the ardunio would send a signal to the base for a certain amount of time, then stop, the amount of time depending on a switch wired to the ardunio for the firing modes such as semi, burst and full auto. This would allow the current to flow from the collector to the emitter, making the motor run for a specific amount of time.
Sorry if that's not very clear, but what are your thoughts? Problems? Any help would be appreciated. (Especially with programming)
(forgot to include trigger switch in the diagram and explanation, it would be connected to the ardunio to control when it sends a signal)
