“Control Cybot from any device that has Wi-Fi and a Web Browser. I wanted to give Cybot Sight, that is, add a camera to Cybot. To do this, I decided to use an ESP32-CAM module. This modification has been …
“Integrated circuits (IC) are indispensable today. They’re made up of many thousands of electronic components (transistors, diodes, resistors, etc.) and still don’t take up much more space than a fingernail. One of the most well-known ICs is the …
“In this instructable we’ll be making a small game console that plays an inverted version of pong. In this version of pong you’ll be dodging the balls instead of “ping-ponging” them over to another player, see how long …
“Abstract This project is about, controlling a fan using 555IC with PWM. PWM is controlled with a potentiometer. I drove a fan but you can use it for a DC motor. The circuit has a back-emf diode. I did this …
“Matching an SO-23 Chip to a TO-92 Footprint. The picture above shows one of my home-brew proto board adapters with an SO-23 chip, in action on a populated and soldered PCB. In the background, a standard TO …
“With the intention of building a cheap and simple color sensor to do projects with our students, we found an idea that seemed to allow us to do this with a simple LDR photoresistor and an RGB LED. Let’s …
“Extremely simple Metal Detector whose making requires only one cheap integrated circuit TL084. It can detect metal coin at 15cm distance, and big plate at more than 50 cm. As I mentioned before, the device is very simple to make …
“A simple web server hosted on ESP8266 to control effects of NeoPixel strip, using NodeMCU Lua Firmware. Why ESP8266 + NodeMCU Lua webserver + NeoPixels ? Neopixels are absolutely fun to work with and adding a wifi control to them makes neopixels more …
“If you are a TV technician this project cannot be missing among your repair tools. I made an infrared remote control with arduino nano that allows you to send 3SPEED and Factory codes (and many others to choose from!) To …
“This Tachometer very precise. it measures too fast or slow RPMs and it can be used to measure engine RPM or any thing. I am currently making an electric Bike, but the problem is that I wanted to measure the …
