How do these LEDs conduct ? With this board: the associated schematic is: P1 (with pins 1 and 2) represents a motor. OUT1 and OUT2 are the conduction paths. LEDs L2 and L1 will illuminate depending on which way the H-Bridge is conducting. My question is how are is that the LEDs conduct at all? It seems that the voltage across the resistor and LED is a function of the voltage across the motor. However, I thought that the voltage across a coil is essentially negligible given the constant current through it. However, are the LEDs drive by the fact that DC motors have inherent internal wire resistance? By my calculations, shown in my other thread regarding the L298 on this forum, I figured that my 3V motor had a 8 ohm internal resistance which demanded a 2.5V drop at 3mA current draw. So that allowed 2.5V to exist across the LED and the associated current to be drawn through it? Correct me if I am wrong on anything stated above.
