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 …

I’ve started to delve into Processing and passing values between Processing and Arduino. If you’re wondering what Processing is, basically its an open source programming language for vizualising data that can interface with Arduino either by reading values/ pins or by setting them. Just remember that they are 2 very different things and require 2 different sketches! This …

First things first, we need to build our circuit. This is the easy bit! We’ll be using the Arduino to control a servo that will rotate our sensor around 180 degrees. The Arduino will then send the value from the distance sensor along with the current angle of the servo to the serial port. Before proceeding please take a moment to check out some of my other work …

This is where all the work is done to read an interpret the values from the servo and the sensor. If the readings are to erratic then you won’t have nice shapes. Also if you don’t allow enough time to the signals to be sent back then you’ll get false distance readings. So this code …
So following on from my previous posts about visualising sensor data in Processing, I’m now looking at drawing 3D representations of the data recorded from the Sharp IR sensor – although can be any kind of range finder. I started by rigging 2 servos, one to pan left to right, the other up to down. The latter is limited to only …

Recently I got a project from Titan industries, who were in search of something as an interactive plant pot which could bridge this gap of emotional communication, in mins this reminded me of brilliant projects done by people where the plant could could tweet and send mails and txts and on your command over the …
Hey everyone, I wanted to share a project I just finished up. I built a super secret locking box for my girlfriends little brother. He has a knack for creative lego building so I thought it would be a good idea to open him up to the Arduino as soon as possible. The super secret …

Once you’re getting some values from sensors, for example using Arduino, (see my previous instructable), sometimes it’s nice to see the sensor data in a graph. Here’s how in only a few steps! I made this particular Instructables using a sonar sensor (XL Max Sonar EZ/AE) but you can do it with any data values that …

I’ve had a cuecat barcode scanner sitting around for over 10 years. Basically it connects to a PS2 port (apparently there is a USB version) like a keyboard and spits out a barcode when scanned. Nice!. The annoying thing is that it is “encrypted”. What I set out to do is; – unencrypt the barcode …
The next board I want to show you is the ADJD-S371 Color Light Sensor Evaluation Board from sparkfun. It emits light and analyses the reflected color spectrum. The board can be controlled via I2C. The sleep and xclk pins were not used in this example. I found a really nice tutorial describing how to connect the sensor to …
