ShotBot - Arduino Powered Pump Project

“This Arduino Pump Tutorial is known as the ShotBot Project, demonstrating an easy way to build a simple shot pouring robot. We use two RobotGeek Pumping stations and some quick code to create a dual shot pouring robot. This project …

Simon Says with LEDs and sound

“Many of us have all played Simon Says where inevitably you find yourself hopping around on one foot while making elephant noises and you wonder to yourself why it was ever a good idea to say “yeah, I’ll come …

SWP Reader Evolution

“For this prototype I decided to stay with plain old through-hole packages and build the analog part in a modular way. The restriction to through-hole packages had a great influence of what parts I could use because most of the …

WaterPi: Houseplant Remote Watering and Monitoring System

“The system is a suitable solution for people who love and want to look after plants in their house but very busy in daily jobs to do that. Growing plants requires time and effort in order to be successful because …

$1 Motor Driver Circuit for Arduino

“The story of this motor shield is that I wanted to make a robot for my multifunctional brainwave controlled system and I decided to share this with you. It’s a very simple circuit I used the L293D IC that …

22 Bit binary counter for Atmega328

“This program will not work on an Arduino Uno. It makes use of features of the Atmega328 chip that are not available on the Arduino. The pins on the 328, and all Atmel microcontrollers, are arranged in banks of eight …

555 Based DC Motor Speed Controller

“555 DC Motor Speed Controller project will control the speed of a DC motor connected to it. This project is built using the popular 555 timer IC.”

5.8GHz (RX5808 Module) open Source FPV Receiver

“First-person view (FPV) is a method used to control a radio-controlled vehicle from the driver or pilot’s view point. Most commonly it is used to pilot a radio-controlled aircraft or other type of unmanned aerial vehicle (drone). The vehicle …

A 3.6V LiFePO4 charger for under 50c

“I like LiFePO4 batteries. They have a rather flat discharge at around 3.2V, which is ideal for powering 3.3V devices without a regulator. You can also use them in devices that take 2 standard AA cells by using …

An Intro and Antennas

“Welcome to the world of wireless know-how in the form of amateur or “ham” radio. Where else can you be an electronics and programming whiz, study solar and atmospheric phenomena, design your own communication system, and provide valuable public service …
