Arduino – (Very) Basic motion tracking with 2 PIR sensors

Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so it turns left when triggered by the left sensor and so on. First have a look at my previous tutorial – Arduino PIR motion detector circuit. ...

Arduino – motion triggered camera

So having worked out that I can make a remote for my Nikon D80 to do some timelapse photography. I started thinking of things I can do to trigger the remote, below video shows it working but you’ll need sound to hear the shutter going. First of all check out my tutorial for making the remote as this builds on that tutorial – also saves me having to recap and explain that. Arduino Nikon intervalometer infrar ...

Water Tank Depth Sensor using Arduino

Water is a precious resource in many parts of the world, and many people rely on water tanks to supplement their water supply by storing collected rainwater or water pumped from a well or bore. But how do you measure how full a tank is? Tanks are constructed of opaque material to prevent algae growth and often kept closed up to prevent mosquito infestation or access by small rodents so it's inconvenient to ...

Motion Sensing Eye using arduino

I have always wanted to make something with my LED dot matrix display, and so when I found a old alarm motion sensor I knew just what to make, a Motion Sensing Eye! This instructable will hopefully finish with you having a working dmd, that will display an eye that opens if something in a room moves (above in the pictures are some gifs of it in action). This instructable will also be updated with bluetooth ...

Weather Station Receiver using Arduino

The incredible popularity of home weather stations shows that it's not just farmers who are interested in the weather. Many people want to be able to track and record weather events within their local environment rather than relying on a state or national weather service that may not have adequate local details. Home weather stations typically consist of two major parts: the sensors that sit outside and mea ...

Security / Automation Sensors using Arduino

Security system sensors such as motion detectors, reed switches, pressure mats, glass-break detectors, infra-red beams, and conductive film can be very handy for all sorts of things including home automation systems, interactive art installations - and sometimes even security systems! Almost all security system sensors provide a simple switched output that changes state based on whether the sensor has been ...

Visual Navigator Making it MOBILE using Arduino

Obstacle avoiding vehicle, continue in “3D Laser Range Finder” series ( project 1, project 2). The basic idea is the same, measuring distance using red laser pointers, CCD analog camera and Arduino UNO.  Modification was made in geometry.  Two lasers were set for “far field” obstacle detection, few meters in front of vehicle on left or right side. Primary mission is to trigger left / right turn before a car ...

ARDUINO Laser 3D Tracking or Range Finder

The idea of using triangulation for distance measurements is well known since Pythagorean time, when his brilliant formula become available for mathematicians. What is new in this design, is lasers power control via “blooming” effect of CMOS camera. Here this “negative” effect was put to work instead of ADC. No need high price “no-blooming” camera!

Compact 3-in-1 Stripboard DIYduino with Integrated Sensor and L298N Motor Shield

I am presenting a compact design of a stripboard Arduino board (DIYduino) that includes a 2A motor driver and has additionally the functionality of a sensor shield. The 2-channel version cost approximately $29.43 and is more affordable compared to $39.00 for a commercially available system consisting of an Arduino Uno, $21.50, a sensor shield, $8.50, and a motor shield, $9.00. The cost can be further reduce ...

Fish Sensing

Overview Once again, my project was motivated by my curiosity to explore interesting and unfamiliar territory.  I decided to see if I could make my own capacitive sensor and then use it in a project of some sort.  After numerous fiascoes with Arduino and computers, I was able to get the capacitive sensor to work and then implemented it into a fishing game.  It was a highly frustrating but really fun project ...

Tiich System – Prototype Final Report

Introduction: Our main goal with the Tiich system is to design a teaching aid/tool which would replace the conventional whiteboard in a classroom environment. We want our system to be used as an electronic based white board, having all the written information easily be saved and submitted to all the students in the classroom. We also want this system to be a touch-based system where you can open certain fil ...
