PWM Power Regulator

“In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the electrolyte. Because the load is purely resistive the simplest solution is a small PWM …

+9V to 60V PWM 2.3A solenoid valve driver using DRV101

“The DRV101 is a low-side power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, and positioners. The DRV101 module is also ideal for driving thermal devices …

MeArm V1.1 - Tiny Open Source Robot Arm

“MeArm is a tiny robot arm that came to Instructables in 2014. Build instructions, cutting files and code for Arduino and Raspberry Pi are shared here, as ever, under a CC-BY-SA licence. Which means please use it, share …

Intelligent Braking system prototype by arduino

“Hi, This Aditya kombe from EuphoLabs Hardware development community brought a new project that is a concept converted to Reality .Here we are making something that is visualized by many automobile companies like here’s demo- So we are making …

12V NE555 PWM Controller Under $3

“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 …

Octopus, a “tentacular” shield for Arduino and Fishino

“Arduino boards and compatible alternatives are really easy use and o powerful, capable of making countless applications, but they suffer from two strong limitations: the relatively small program memory and the limited number of available outputs, especially when coming to …

PWM Solenoid and Valve Driver using DRV103

“Tiny module is a PWM Solenoids and Valves driver using Texas instrument’s DRV103 low-side DMOS power switch employing a pulse-width modulated (PWM) output. Its rugged design is optimized for driving electromechanical devices such as valves, solenoids, relays, actuators, motors …

Homebrewing and Arduino: the perfect recipe

“Home-brewing can be summarised in the hobby of make beer at home and for sure is a wide spread passion all over the world including Italy where I live. Home brews are basically small scale craft beer makers and generally …

LED Persistance of vision Globe

“This is a project similar to the one already published, but upgraded. It consists of 64 LEDs and 90 columns, so the resolution is 5760 pixels. I also used the shift registers, but 8 of them, one for every 8 …

Java ME 8 + Raspberry Pi + Accelerometer + PWM + Motor Driver = JBalancePI Robot (Part 1)

“Learn how to build a two-wheel self-balancing Java robot using Raspberry Pi. In my last four-part series of articles, I explained how to connect electronic sensors or devices to the Raspberry Pi 2 Model B using various interfaces: Part 1 …
