This guide describes the pinout of the ESP32 development board and concentrates on ESP32 devkit, in particular. Actually, the ESP32 devkit comprises of the ESP-WROOM-32 which actual implementation we shall be implementing throughout the two main modules. It is worth admitting that there are several different chip models of the ESP32 family in the market. […]

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The

What’s up my friends, welcome back. What I want, is the aluminum block below to have let’s say, exactly 100 degrees. I’ll control the real temperature using a K type thermocouple. To read the data I’ll use the MAX66 75 breakout module and control the PID algorithm with and Arduino. Finally, to apply power we

1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET Preset PR1. On board 1W LED

Entries into the Circuit Sculpture Contest tend to be pretty minimalist by nature, and this LED candle by [Amal Mathew] is a perfect example. The idea here was to recreate the slim and uncomplicated nature of a real candle but with a digital twist, and we think he’s pulled it off nicely with a bare minimum

Further to my instructable 12V NE555 PWM Controller for Under $3 I have designed and built a simple and cheap DC Motor Direction Controller that can either be used with the PWM Controller, for speed control or by itself with a 12V power supply. I designed this DC Motor Direction Controller so that I could

While making my mini table saw I bought a 12 V motor speed controller module from eBay. Fair enough, I thought … that was an easier and straight forward solution. But then I decided to make my own. I did some hunting around on the interweb and found a pretty good starting point in Circuits

As the hardware is at the point of initial release, but the firmware and GUI aren’t quite there yet, I decided that it would be prudent to split off the firmware and GUI components into their own GIT repositories. Tracking all files in the same repository was convenient through the initial stages of project development,
