The 555 Night LED Breather is a multistage kit that combines a light detector, a 555 astable oscillator, and a RC charging bank to produce a night activated LED beacon. When the light level falling onto the kit falls below a defined level (using the potentiometer), the circuit enables the 555 astable oscillator which in turn makes an LED slowly turn on and off. The rate at which the LED is turned on and off can be adjusted with a second potentiometer and this kit is ideal for night beacons and path indicators. This kit is great for the classroom and can be constructed in under an hour by most students.
