Hello! My name is Igor. I am interested in programming and developing various devices. It’s always interesting for me to create something new, unusual. This vet is breathtaking when a lifeless piece of iron suddenly begins to move, ride, fly, and perform all the actions that you invest in them. Feel like a creator of something very unusual! I am fond of programming Arduino, STM32, ESP8266 and ESP32. On this channel you will find simple and interesting things, and most importantly: you can repeat all this, and even do even better!
