I took electronics back in college, but I'm quite rusty since its been well over 15yrs now. However I do have the knowledge to purchase whatever electronic components I need and to also solder them together. Here's what I need. I'm working on a "tool", to simplify a task. Basically I need a circuit that will activate a small DC motor when a push button is pressed. It would be best if the speed at which this motor operates, could be adjusted. Now, this motor will continue to operate until an "open" circuit closes.
I'm having a tough time explaning myself so lets use this example. Lets say we connected a DC motor to a continuity tester. I push a button, the motor starts to spin at a speed which I can regulate. I take my positive and negative leads on a continuity tester, join them, hence closing the circuit, and the device (motor) immediately shuts down. The procedure can be repeated again upon the push of the button.
I hope that makes sense. Hopefully someone can put something together for me that'll operate on say a 9V battery, making it portable. In case you are wondering, this motor should be something similar to a small remote controled car.
Thank you! I hope someone can help me out!
