We have a great thread that contains lots of info on thermal differential controllers here. However, I wanted to start a thread dedicated to my own development of a thermal differential controller that I’ll be using for my attic heat reclamation project. Tonight I setup a simple circuit that tested the operation of the differential […]

A Simple Bat Detector based shield for the Arduino Uno
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 […]
How to make (and connect) a soft potentiometer
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 […]
Arduino UNO Tutorial 8 – NightLight
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 […]
1 LED Game with Arduino Uno and an RGB LED
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 […]
LED aquarium lighting with an Arduino based PWM timer
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 […]
Ground Tracking LED Longboard Mod
This mod uses a custom designed encoder on one of the wheels to track where the longboard is on the ground and light up the LEDs so that the light pattern remains stationary on the ground as the board moves over it. To make doing this instructable as easy to understand as possible, you will […]
Arduino Clock using Standard Clock Display
This is a relatively simple clock to build, in terms of the hardware required and in terms of hooking up all the wires. The complexity lies in the software, which I’ve conveniently included as part of this instructable π This instructable illustrates a few things: * Keeping relatively accurate time on an Arduino without using […]
Getting Things to Talk: Arduino + LCDs
I spent the better part of the day on Saturday doing some more basic research into connecting an Arduino and LCD for this ongoing project. For the most part, itβs pretty basic and following the wiring diagrams and tutorials online is fine. I ran into a problem with getting text on two lines, which Iβll […]
Arduino ISP – Lazy Old Geek (LOG)
Arduino ISP – LOG So this Lazy Old Geek (LOG) has had a lot of trouble getting Arduino bootload on Atmega chips. I couldnβt get either of these to work with Arduino UNO Rev3. http://arduino.cc/en/Tutorial/ArduinoISP http://letsmakerobots.com/node/35649 So I developed a couple that worked for me: http://www.instructables.com/id/My-Arduino-Bootloader/ http://www.instructables.com/id/UNO-Bootloader-In-Circuit-Programmer-1/ Problem: Well, my second Instructable works good for […]
