Bike light kit 

Self assembly bike light kit using a 555 timer with a varaiable resistor(potentiometer) to control the frequency of which the LEDs  flash,. 

The 555 timer chip is a very versatile IC, because when connected correctly, it can it can create pulses of current at specific time intervals decided by the resistor-capacitor (RC) network. When a 555 timer creates pulses in this way, the LED doesn't stay constantly on. It only turns on at a pulse and then shuts off after the pulse has passed. And it does this in a never-ending cycle, which creates the flashes of the bike light.


To make the 555 timer chip create pulses, it must be placed in astable mode. Astable mode simply means that the 555 timer has no stable state. It switches constantly between high and low, or on and off. This is why this mode is also called oscillator mode, because it uses the 555 timer an oscillator, which creates square wave signals.

 Warning: Choking Hazard - Batteries and small components are extremely dangerous if swallowed.
