FarmBot is an open-source CNC farming machine designed for small-scale precision food production. Similar to any CNC milling machine, FarmBot hardware employs linear guides in the X, Y and Z directions for tooling. FarmBot tools include: seeder, watering nozzle, camera, weeder and...

Alvaro Villoslada designed an open-source muscle-machine to control any kind of electronic device through the myoelectric (EMG) signals. The name of this project is Mumai and it is published on hackaday.io. “The Professional EMG systems are very expensive, cumbersome and...

Sparkfun has a simple-to-use and open source solution for measuring weight and temperature. All you need is a load cell hooked up with OpenScale. You may find a variety of high quality weight sensors to be used in this project on Flintec load cells. OpenScale uses HX711, a 24-bit...

Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for...

This tutorial shows how to interface DC motors using L293D motor driver IC and Arduino. Controlling DC motors with Arduino and L293 -...

Espressif announced ESP8285 a Wi-Fi chip for wearable devices on May,2016. Some described this chip as the killer of ESP8266, that is because ESP8285 includes an embedded 1 MByte flash memory. This means smaller area in PCB is needed to include your Wifi chip while the old ESP8266 needed...

This tutorial is going to teach you the basics on using OLED 0.96inch LCD128x64 with Arduino. OLED 0.96 inch is a monochrome graphic display module with a built-in 0.96 inch, 128X64 high-resolution display. OLED 0.96inch is able to work despite the absence of backlight. In a dark...

Florian Wolters made his own version of MMDVM adapter: During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called the...
