Hi..
I am trying to build a circuit using an LDR and timer-555 ic, the circuit is intended to turn on 10 white LEDs when it gets dark and i wish to power the circuit using a 3.7v battery, but the problem i am facing is the output(pin 3) of 555 cannot drive 10 white LEDs In their full power! But LEDs can glow in their full power when i connect them directly to 3.7v battery!! Are there any ideas or circuits to light the LEDs in their full power? (maybe a transistor amplifer?).
The posted circuit have some errors that it turns on leds in daylight instead of darkness..so i fixed them by changing the LDR and VR in opposite
