Hi,
I am making a circuit for a led chaser. the leds should glow one by one.
I am testing the circuit with one led for each transistor later I will add array of leds to each transistor.
I want the base resistor value to make the transistor turn on. Leds will have resistors to limit current to them.
Problem is : first led is glowing continuously, second one is not glowing and third one is glowing dim but continuously. they should glow and turn off one by one.
Voltage used is : 12v DC
