Are you an electronic hobbyist? Then an adjustable power supply is a must for your various needs. This project explains how to make a LM317 based adjustable power supply unit with a digital display. Components Required 1. LM317 IC 2. Resistor – 240 Ohms 3. Capacitors – 0.1uF, 10uF 4. Potentiometer – 5k 5. 30V/1A Adapter (or a …
A couple of years I embarked on my own home automation project. It started off by building a server controlled 433 MHz transmitter build with an Arduino to switch lots of cheap PT2262 based remote switches. Later I added an Arduino based receiver for my weather station, hooked up the control contact of my EV …

In this post I will attempt to describe the steps I took to build the arduino based thermostat shown in the following videos. The first video was taken when around just half of the coding of the menu system was complete, but gives you a basic run through of the features. This second video shows …
I have loved making projects with Arduinos, but at $30 a piece your projects can get expensive. So I want to show you how you can make your own Arduino from scratch and save money doing it. Make your own Arduino for around $8. For this instructable I show you how to make one on …
The one wire Digital Temperature Sensor – DS18B20 from Maxim (formerly Dallas) is a great chip for measuring temperature in your projects. Luckily, there is a Dallas Temperature library for the arduino which makes using this sensor very easy. The most recent version of this library can be found at http://www.milesburton.com/?title=Dallas_Temperature_Control_Library We used version 3.6.0 …

Sous-vide cooking allows you to precisely control the temperature of cooked food (how “doneness” is measured) by immersing it in a carefully controlled water bath. It’s possible, but seriously difficult, to do this just with a thermometer and a pot on the stove… but if you have an Arduino do all the hard work for …

Things used in this project Hardware components Arduino MKR1000 × 1 Breadboard (generic) × 1 Temperature Sensor × 1 Photo resistor × 1 Moisture sensor × 1 Resistor 10k ohm × 1 Software apps and online services Johnny-Five Story This is a simple …
Scopeclock is an easy to use hardware to make your X-Y capable analog oscilloscope more useful .Using this simple to use hardware you can convert your analog oscilloscope into a scope clock.This project was me and my friend kshitij gupta at CEDT nsit under the guidance of Prof. Dhananjay V.Gadre. Scope clock has two modes …

I was working on a project were I needed a cheap and efficient way to log the changing resistance of a sensor while simultaneously logging the temperature. This project is similar in many respects to the other data loggers on my site. Three prototypes have been built with the third one being a PCB. I …
Introduction This is an Arduino controlled light sensing switching unit. Its main use is to control solar lights to turn on when it is dark outside, but it can work in many more applications. This guide will walk you through every aspect of the building process. Prior knowledge of the Arduino unit is not necessary …
