ON Time delay timer by using One NPN Transistor and Capacitor
This video how to make ON time delay timer by using One NPN transistor and Capacitor, This LED glowing for a few seconds when the power is turned on. The circuit relies on the (10uF to 3300uF) discharging into the rest of the circuit so that it is uncharged when the circuit is turned on again.you can change the time delay ON increase of (uF) capacitor value.
This circuit does not appear to work. Its been suggested that the transistor type is incorrect. Could you please confirm the transistor type number. Thank you.
Without assembling this circuit, I have noticed that the 1M resistance and the capacitor need to exchange places for circuit to work properly. That is all.
