This ible is for the building of my small, almost matchbox size, arduino compatable board. As seen in this ible.. http://www.instructables.com/id/Pocket-Ardiuno-kit/ I experemented with the one in this ible to see how it can be impreoved, but the consept is the same and so is the build to a degree. Origonally made as a pocket […]
As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14: Since writing this article, I have developed a new hardware platform which has been specifically designed for this product. The main board has an integral power supply and RF module, and there is […]
In this tutorial you will learn how to communicate with a computer using a MAX3323 single channel RS-232 driver/receiver and a software serial connection on the Arduino. A general purpose software serial tutorial can be found here. Materials needed: Computer with a terminal program installed (ie. HyperTerminal or RealTerm on the PC, Zterm on Mac) […]
I just brought a new lamp and after a week, I’m tired of looking at it randomly change colours between red, blue, green. What can you expect from a cheap lamp brought at 5$ . Looking at the lamp I realized that I could make a Gmail lamp, that shines green every time I got […]
This article describes a simple spectrum analyser for the 2.4 to 2.5 GHz Wi-Fi band. It’s based on the Cypress CYWM6935 Wireless Radio Module. Although the manufacturer doesn’t recommend it for new commercial projects, it is still widely available from eBay suppliers and Farnell here in the UK. The module has 1 MHz channel spacing […]
I’ve built a number of projects that have interfaced the output of the Simple Bat Detector with a microprocessor. The most recent was the BatLogger II. But I hadn’t come up with an easy way for others to experiment with this idea … until now. My friend, Frank, in Germany, had wanted to make a […]
This instructable will tell you how to make and connect a soft potentiometer to a microcontroller, in particular we will connect it to a Lilypad Arduino. In our case soft potentiometer means a potentiometer made of a textile conductive ribbon. What you need: 1. soft conductive textile ribbon. The important thing here is that the […]
In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor. For the LDR we are […]
Sometimes I just have those days where I really want to make something neat with the Arduino I have lying around, but I know I don’t have the patience for a more involved project that’ll take more than a day or so. This is for one of those days. The premise is as follows: A […]
I bought a small aquarium (54l) as an impulse buy and I needed some lights for it, so naturally I wanted to use LEDs. I also needed a timer for the lights. I also wanted the lights to fade in and out when they were going on or off as a cool effect. I ordered […]
