Super Simple Arduino Load Driver V2.0. Now control Polarity!

This is version 2.0 of the previously successful kickstarter project I launched last year.  I have a ton of these PCB boards left over and it got me thinking.  Why not find a P channel MOSFET with the same pinout and use it to control the direction of the motor also. I looked around and found the IRF5210.  I ordered up a batch and tested them out.  All thats left to do now is order a large quantity for the ...

Measure Capacitance with Arduino

This tutorial provides a guide on how to set up an Arduino to measure the capacitance of a capacitor. This can be useful if the capacitor is unlabeled or if it is self-built. Capacitance is an object's ability to store an electric charge. Reasonably, this object is referred to as a capacitor. A capacitor that stores this charge in an electric field between two conductive plates is known as a parallel plate ...

How to use an RGB LED – Arduino Tutorial

An RGB LED has 4 pins, one for each color (Red, Green, Blue) and a common cathode. It has tree different color-emitting diodes that can be combined to create all sorts of color! Any color is possible depending on how bright each diode is. In this tutorial you will learn how to use an RGB LED with Arduino and create unique color combinations. So, let's get started! Step 1: What you will need For this tutoria ...

Wino… Like Arduino, Only smaller

The Wino board is an Arduino-like stackable development system which is both smaller and cheaper than Arduino units and features built-in WiFi as standard. The main Wino controller board measures 26.5 x 18.5 mm and fitted with an Atmel ATSAMD21 running at 48 MHz with 128 kB Flash storage and 16 kB RAM. The board uses the ESP8266EX WiFi module which supports all the 802.11 b/g/n standards offering P2P and so ...

Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

An Arduino me-too-alike for PIC16F873A

We’ve all done it – looked sideways with not a little envy at a range of add-ons for a power tool, and wished that they were available for the one we bought. There is no ’standard’ footprint for a PIC Micro-controller development/experimental board. Vendors have chosen to provide their own ‘take’ in each case, and who can blame them, selling ‘add-ons’ for a proprietary board increases revenue streams. Given ...
