This motor driver circuit can drive a brushed DC motor with up to 250W of continuous load. The project can be controlled with the general logic IO-Ports of any microcontroller. Either an Arduino Uno or another microcontroller can be used as the control board. The project uses two...

Today we are going to build one of the most important tools in sound mixing; A audio VU (volume unit) meter based on an Arduino/AVR microcontroller. This project serves to demonstrate how the knowledge of electronics can be applied to build solutions for any part of your day to day...

Hygrometers are used to determine the moisture content of the environment. They find application in farms, food storage, museums, and other places where moisture needs to be monitored to ensure damage is not done to goods and other things stored in that space. For today's tutorial, we are...

USB Morse Keyer is a microcontroller-based auto keyer with following features: USB / straight key / iambic key inputs. Support for both standalone and USB operating modes. 64-character USB typeahead buffer and 6-character Morse key typeahead buffer. Support 5, 10, 15...

Over the past few tutorials, we have explored different projects that involve building GUI interfaces and menu on the Nokia 5110 LCD display. For today's tutorial, we will do something similar to that but we will kick it up a notch by introducing a GSM module which will help us put a...

Isolated high power Mosfet DC solid state relay shield allows you to control high current DC load in switching or PWM control mode. The project can be used in wide verity of applications like DC-DC Converters, inverters, DC motor control, solenoid, LED Dimmer, battery chargers and it...

Interested in controlling an object or device without physically touching it? So am I! For today's tutorial, we will look how to build a DIY based Gesture Controlled Robotic Arm using the Microchip MGC3130 based, Seeed 3D gesture and position tracking shield for Raspberry...

Since it's inception the Arduino IDE has demonstrated the desire to support all kind of platforms, from Arduino clones and variations of different manufacturers to third party boards like the ESP32 and ESp8266. As more people get familiar with the IDE, they are beginning to support more...
