Arduino + Processing – Make a Radar Screen to Visualise Sensor Data from...

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...

Arduino + Processing: Make a Radar Screen to Visualise Sensor Data from...

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...

Arduino – Using a Sharp IR Sensor for Distance Calculation

Well, looks like my sonar sensor (SRF05) is a just a tad inaccurate for precise measurement as I found from my radar screen I made (Arduino Radar Sscreen). So I’ve got hold of a Sharp GP2Y0A02 series...

Arduino + Processing – Make a Radar Screen – Part 3: Visualising the Data...

So I had some luck with getting the Sharp Infrared range finder working and I’ve now plugged this on to my servo rig to see if I get better results on my radar styled display. Check out how to use the...

Arduino + Processing – 3D Sensor Data Visualisation

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...

Using Processing to Send Values using the Serial Port to Arduino

In this write-up, I’ll show how to create a value in Processing and then send this value over the serial port to the Arduino. In the example I’m setting values of LEDs making them brighter or dimmed...

Arduino: Controlling the Robot Arm

So the arm is wired into Arduino as per the previous post, Arduino: Modifying a Robot Arm and hopefully this has worked. In this next part I alter the Arduino sketch slightly and write the first...

Arduino – Redefining the TV Remote

We use them every day, but has no one got bored of pressing buttons on a stick, it’s far too much effort pressing buttons! Surely there are better ways to control a device? After doing some work with...

Arduino Robot Arm – LarryArm v0.1

[ad#Google links] I have constructed a basic Arduino robot arm using 3 servos that cost me £15 in total plus a couple of hours in time to build and it’s very simple that I think anyone can replicate...

Arduino : Convert Decimal to Binary

When programming Arduino you’ll eventually at some point want to get to converting decimals to binary or the other way around. In most cases it’s normally because you want to read a value and set a...
