In our previous tutorial Getting Started with the RASPBERRY PI ZERO, we had an overview Raspberry Pi zero W and setup the Pi Zero. In this tutorial we are going to design a simple LED circuit and ...

This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...

You must have seen different kinds of decoration lighting patterns. In this LED chaser circuit, we have created an interesting LED blinking pattern by using a 555 timer IC and Counter IC CD 4017.

This is a simple flashing led circuit with 2 leds and 2 NPN transistors. It illustrates the behavior of transistors and capacitors and if you use an oscilloscope it will be very easy to determine what ...
