In this video I will show you how to make a touch sensor using a 555 timer that switch the led to turn on and off. The circuit contain 2 led and when the other led1 is ben turn of then the led2 will turn on and reverse happen when the led 2 turn off. The 555 timer is one of the most use Integrated Circuit (IC) in a project because of the different function that we can made it do. The most common use of the 555 timer oscillator is as a simple astable oscillator by connecting two resistors and a capacitor across its terminals to generate a fixed pulse train with a time period determined by the time constant of the RC network. If you want to learn more about 555 timer I highly suggest you watch element14 presents video about the 555 timer, this youtube channel help me to understand the 555 timer with a better insight.
