We have seen that Multivibrators and CMOS Oscillators can be easily constructed from discrete components to produce relaxation oscillators for generating basic square wave output waveforms. But there ...

In this project we are introducing a simple circuit and code that will allow you to create fully programmable and customizable earrings. We are also leveraging the mighty power of the ATtiny85 ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...

This circuit can be used to test up to three LEDs at once, connected in series. You can easily increase that number by using a higher supply voltage. If you do so, you should allow 2.7 V for each ...

In this short tutorial, we will show you how you can build yourself a transistor-driven color-changing RGB LED lights. The building process is simple and requires only a few transistors, capacitors ...
