Hello, Toady in this post I will share a small project. The Project is How to make a 555 timer ic testing circuit. you can make this circuit using only 2 Pcs resistor, 1 pcs capacitor and 1Pcs led for output . You can use this circuit as a led flashing or led blinking circuit. and you can adjust the blinking speed by changing the capacitor value. I used a 10 microfarad capacitor here.you can increase the led blinking speed by reducing capacitor value. For example, you can use 1uf, 2.2uf, 4.7uf … capacitor for increase blinking speed. and you can also use this circuit as a 555 ic tester. so let”s make it…
