A builds

Hello everyone Welcome to My channel, Today I am building a simple touch less switch, it’s activated by just waving our hand with the help of Infrared sensor and 555 timer IC so let’s build it…. Its operation is simple as the 555 working as flip-flop its store the previses state of input and the output change each time when input gets changes. The 555 timer in bistable mode i. e. as a flip-flop can be used in low speed, non-computer applications like robotics. A simple application is a robot which moves forward and backward every time it hits an object.

It just work fine in my circuit as high voltage apply to the base of the transistor current star flowing from collector to ba
