A quick demo video for your pleasure. This is an instructable for a target practice system for airsoft and nerf weapons. The system has been designed to test a shooter’s reaction times and accuracy. Sam and I have been meaning to do this project for a while, and when the microcontroller competition opened, coinciding nicely with […]
UPDATES Feb 20, 2013: In response to a question by student Hala Abuhasna if you wish to use the .NET Serial class, use the naming convention “\\\\.\\COMn” and replace n with a number > 9 to define your com port for COM ports above 9 such as COM10, COM11, etc. Mar 23, 2012: Featured on […]
Arduino Leonardo Introduction: Arduino Leonardo is a microcontroller board that uses ATmega32u4 (datasheet) as the main chip. Most of these include twenty digital I/O pins out of which seven can be used as PWM outputs and twelve can be used as analog inputs, sixteen mega Hertz crystal oscillators, micro USB connection, power jack interfaces, ICSP […]
This is a beginners project for the Arduino. I am using the Arduino Uno but should work with little or no modification on other arduino models. Setting up the hardware is very easy. This project is more of a training tool for learning how to program a timer list while listening for a button press. Parts […]
A simple temperature sensor using one LM35 Precision Temperature Sensor , Humidity Sensor and Arduino, so you can hookup on your future projects. The circuit will send serial information about the temperature and humidity so you can use on your computer. I have taken data from my compost. The project is related to an existing […]
This is a step by step guide to build an autonomous navigation robot. We use the Arduino microcontroller to control this robot. We have two different programs for this robot. The first enables the robot to drive around and avoid anything that gets in its way. This avoiding obstacles program uses two ultrasonic sensors. Our […]
Make your own, custom AUTONOMOUS SENTRY GUN! A Microcontroller Contest Finalist and Runner Up Winner. This instructable is out-of-date. For the most recent version of the tutorial, see the website . Cheers! This sentry gun autonomously tracks, aims, and shoots at targets, using: -An airsoft or paintball gun -A webcam to find targets -A computer to […]
This was one of the first programs i wrote for the arduino after having it a few days 🙂 we will be making l.e.d police lights with minimal materials Step 1: You will need. You will need Arduino (or suitable clone) Breadboard 2x 240ohm resistors 1x Clear Red l.e.d 1x Clear Blue l.e.d Some Jumper […]
Hi, all! Today I’ m trying to explain you my last project: “The morse code generator by a PS\2 keyboard” I’ ve used an PS/2 keyboard to send input to my Arduino board (like described in here) and transform it in morse code that activate a speaker and a relay. Components: – PS\2 keyboard – […]
This instructable is a quick write-up of my experience creating a multifunctional moodlight. Some basic knowledge of electronic circuits is expected. The project has not yet finished, some adding functionality and tweaking has to be done but it is already functional. If you guys are enthousiast about this instructable I will update it. At the […]
