Hello
I am working on a project that I need to detect when the circuit is energized, the circuit feeds a dc motor 4.5 volts operates forward and reverse by changing polarity. I want to light a led when in forward and another led when in reverse. I put two leds in parallel with the motor each led polarized opposite of each other, Each led lights depending on rotation of the motor or current flow, only problem with this is the motor speed is reduced due to the reduction in current caused by the parallel led.
What i need is a circuit using a transistor to sense the voltage then acts as a switch to turn the led on via separate circuit. I assume I will need 2 transistors to accomplish forward and reverse.
Thanks for the help
George
