LED Circuit Schematic - Astable multivibrator lights LED from a single cell

 

The simple astable multivibrator provides a low-cost way to drive an LED from a single cell. Lighting LEDs from a single 1.5V cell poses a problem because their forward voltages are higher than the cell's.

  1. Thanks for share this pcb layout and i will try to make it custom pcb board for it.

  2. I've tried putting the LED in both locations, like it is here across the L1, and also across the transistor Q3. I think that the 1.5V cell adds to the L1's voltage when the LED is across the L1, making it easier for the circuit to light the LED. Thanks fore the circuit schematic.
