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 th... Read more
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 st... Read more
This tutorial is about pinout of the ESP32 development board, especially for ESP32 devkit. ESP32 devkit consists of ESP-WROOM-32 module. There are many versions of ESP32 chip... Read more
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 uncom... Read more
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, f... Read more
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... Read more
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 int... Read more
Hardware components: Arduino UNO & Genuino UNO × 1 Atmel ATTiny85 × 1 DigiSpark × 1 Plastic box for electronics × 1 Jumper wires (generic) × 1 IRF530 × 1 Resistor 1k ohm × 5 Resistor 100... Read more
This is something we have been asked a lot about. How do I control a ton of Servo motors with my arduino? Well… using the TLC5940 is one way. And this nice break outboard from sparkfun makes... Read more
This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get star... Read more
