Can anyone make this and post an instructable?
IC1: LM555 Timer IC
Q1: 2N3906 PNP transistor
R1: 100K potentiometer
R2: 3.9 Kohm resistor
R3: 10 Kohm resistor
R4: 47 Kohm resistor
C1, C3: 0.01-µF disc (non-polarized) capacitor
C2: 1.0-µF electrolytic or tantalum (polarized) capacitor
Speaker: 8-ohm, 0.5-watt speaker(i also tried a buzzer)
Photoresistor: I used a LDR aren't they the same?
The buzzer goes off(not off. it's like explosions"The bomb went off") when light hits the photoresistor.
