Overview This is a guide to building an Arduino-powered clock that uses LEDs to display a 24-hour clock (hours and minutes) as binary digits, an analog meter to display the seconds, a switch to toggle between time-display and time-setting mode, and 2 knobs for setting the hours and minutes. This was designed from scratch, but […]
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 Processing sketch to test control of the arm – video at the bottom. To control the robot arm we’ll […]
What is Clusterbot? He is a small, affordable, autonomous Arduino-powered robot. He can move, see, avoid obstacles, and makes a melodic chirping sound sometimes. Clusterbot was my first Arduino project, and I think he makes a great project for a beginner. While building Clusterbot you will learn how to use motor controllers, ultrasonic rangefinders and […]
I started with an idea of what I wanted to do from the beginning but one attempt after another I finally got to where I am now. This robot can be remotely controlled from anywhere in the world and driven around the house. I can see through it’s eyes. Here is a brief run down. […]
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 but this example can be extended to control other items – which I plan to do later! Basically […]
This project used the Si470x FM radio receiver and an ardurino to make an over the counter kitchen radio. These parts had been purchased for a different build that unfortunately met a premature end. The concept for this project is simple. Play my favorite news and music radio stations while having a form factor that […]
If you touch the package, it will scream and run away–changing its course when it strikes an obstacle. When you lift the gift tag, light strikes a photocell and operation commences. Motors and a sound module are controlled by an Arduino (and Arduino Motor Shield). Major components required are: Motorized toy–Kid Galazy Morphibians Rover Remote […]
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. […]
This is a little art project I made with 95 RGB LEDs arranged in a 3D cylinder shape, sitting atop a microcontroller-based driver circuit. The LEDs are individually addressable, and when you power it on, the software cycles through a series of animations, e.g. various moving rainbowy patterns, “rain”, “fireworks”, and so on. It doesn’t […]
Ah yes, it’s time for another Instructable involving an Altoids tin… But this time it’s not about what’s inside the Altoids tin, it’s about the Altoids tin itself. In all its greatness, the Altoids tin we all know and love has one rather major flaw for DIY electronics use: it’s electrically conductive. To combat this, […]
