The circuit presented here is about a boost converter based on LM2698. It is a PWM boost converter from Texas instruments. LM2698 can also be used as a flyback converter. The current mode architecture is a special feature of LM2698, which provides superior line and load regulation. This...

runtimeprojects.com has a tutorial on how to use 433Mhz modules to communicate between 2 Arduinos. The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is...

David Cook built a 5V regulator to sit atop a 9V battery: For quick portable projects and temporary hacks, it is often faster to reuse a simple 5V regulator circuit than to integrate a power supply into the device design. My toolbox has an LED tester and magnifier light, so why not...

circuitbasics.com has a tutorial on how to measure capacitance using arduino. With all the different ways capacitors are labeled, figuring out the values of your capacitors can be challenging. Especially if you don’t have a digital multi-meter to test them. In this tutorial,...
