The purpose of this instructable is to introduce the sketch writing fundamentals to all new comers to the Arduino world. It is meant to be a beginners guide that includes detailed explanation about the basic statements and functions. Most of the sketches I use are taken from the Arduino IDE for their simplicity. I wrote

What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic

This project is an update of one of the previous model railroad automation projects, The Model Railway Layout with Automated Siding. This version adds the feature of coupling and decoupling of the locomotive with the rolling stock. The operation of the railway layout is as follows: The locomotive will start from the mainline and proceed into

To get started with Arduino, you’ll need some basics. In this tutorial, we’ll go beyond a little blinky light and teach you about: Variables Input and Output pins Sensors and reading data Mapping results Functions In another tutorial, I’ll cover classes and why we might use them. But, we might still make a little light
This project came to my mind when doing my MEM (Mechanical Engineering Measurement) project, a subject in my B.tech. The idea is to measure the angular velocity of my bicycle’s wheel. Thus knowing the diameter and the all time mathematical legend the pi(3.14) the speed can be calculated. Also knowing the number of time the wheel has

Hi everyone! I’d like to share the project I have been working on here. I got inspired to experiment with capacitive touch sensing through a project in my university. I found out about this technology through instructables and used the things I learned here and from other places on the internet to build my own

Green Lights is a project that was created to teach students about physical computing. This includes Inputs and Outputs, Electricity, programming with Arduino, and a little bit about traffic control systems. The intersection will be setup at the front of the classroom and students will be split up into teams. Teams will be given note
Controlling a model train layout with a wired throttle and turnout controllers might be a good start for beginners but they pose a problem of non-portability. Also, the wireless controllers which come in the market can either control only some locomotives or are a bit too expensive. So, in this instructable, let’s learn how to

Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout

This is a standard Arduino example sketch, copied here for reference. Full Source Code The full code is all in one file Blink.ino. /* Blink Turns on an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the Uno and Leonardo, it is attached
