Today’s project is not going to be based on evive. Today, we’re going to make yet another smartphone-controlled robot but this time using ESP32. It can move forward, back, right, left, and doesn’t need Bluetooth! We’re to program it in Pict... view more

Recently, I came across the RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less w... view more

The I2CScanner library is instantiated through its constructor. The object contains as variables the address range for Low_Address and High_Address scanning. The object is initialized through the Init () method. There are three families of methods. The Scan methods work in ... view more

This is a simple latch circuit. Press the button once and it will turn on the output. Press the button again, and it will turn off the output. Instead of a push button, you can use a vibration sensor for example, and turn on your devices with the latch each time you sense a vibration. See belo... view more

What’s up my friends welcome back. Today we will look at a very basic circuit but also quite interesting. If you are into electronics I bet that you’ve heard about inverters. We have the rectifiers that pass AC voltage to DC voltage and then we have the inverters that will pass DC voltage to ... view more

MCB which stands for miniature circuit breaker and we can have it of 1 pole, 2 pole or more. The main purpose of this device is to break the circuit in these two cases:- First, when we have an over load connected during a certain amount of time.- And second, when we have directly a short circuit.... view more

Well, you could just go to eBay and buy a kit like this one with everything ready for assemble. But that is not as fun as making one. In this tutorial I show you how I've made my own acrylic display with RGB LEDs and adressable LED strip, so we could place multiple displays in series. B... view more

Unless you’re very good, personal synths are fun for you — though often quite annoying for onlookers. After making his own wristwatch-based synth in 2016, Clem Mayer decided to build a new version that’s larger and louder than ever, and programmable via an Arduino contro... view more

A Tesla coil generates a high frequency high voltage inside of the main coil and that ionize the air at the end of the copper wire and the air will glow due to the created arcs. Depending on the tesla coil power, the arcs could ger bigger. This project is very cool to look at but not just that. I... view more

Crystal or ceramic resonator and then we have the oscillator. What is the difference between these 3 elements, why we need them in our circuits, how each of these works and what configurations do we have. In this post we will see all that. I’ll try to explain the main differences between crysta... view more

Around 2 years back I've made a huge portable Bluetooth speaker but that had some errors with the circuit. Then, I've made a small portable bluetooth speaker that had a good circuit. Now, I'me making a new version for the big speaker but with all the errors corrected. It will have a 6S battery pa... view more
