Arduino LED Scroll Bar

In this post we are covering a detailed DIY project to build an Arduino based LED scroll bar, as shown in the below picture.

This is quite simple project and only requires Arduino nano and few LED stips, along with some other basic electronic components.

So go through the link below to find the circuit diagram, PCB files and a detailed guide to build this beautiful LED scroll bar.

DC to AC Inverter Circuit

Inverters are quite handy in time of power cuts. The most common type of inverter we see in everyday life is UPS (Uninterruptible Power Supply). We use UPS to keep PC (Personal Computer) running in the event of power cuts. UPS keeps up the power delivered until battery bank runs out.

UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. In this tutorial we are going to design a 100 watt 12v DC to 220v AC inverter. This Circuit is easy and you only need few capacitors, resistors, diodes and a transformer. So here the guide and schematics to build this inverter circuit.
