The idea for this project came from one of my favorite ‘ibles: the polargraph. I loved the drawing style and thought how cool would it be to do this on the side of a building? Unfortunately the challenges to setting up such a large polargraph on a student budget pushed me to find an alternate

This is a Line Following Robot. It follows a black line that is drawn. It is able to detect the black line through one photocell and one analog light sensor. There is an LED in between the two sensors that gives off red light when the Arduino is powered on. Then, when the light is

Servo Cable The continuous rotation servos that come with the BOE Shield-Bot have a 3-wire cable for connecting it to the power and controller. The black wire is the ground, the red wire is the power (positive) and the white wire (sometimes yellow, depending on the servo) is the signal wire. The signal wire is

One of the coolest projects I have done so-far with my kids is a “near-space” balloon. That’s not quite into space itself (100Km+) but so high that the sky looks black and you can start to see the curvature of the earth below you. The Flickr set with the photos from our first launch is

In this Instructable I wanted to show to you how to make a self balancing robot. What makes it unique is that its exterior is made to look like the Instructables Robot. Internally it works in the principle of PID, it is a very popular control system for maintaining a variable from fluctuating. In this

One of the simplest ways to get a motor to turn in both directions is by using a double-pole, double-throw (DPDT) relay. Along with the relay, this hookup requires two transistors and two Stamp pins, one for on/off control and the other for direction control. The diagram below contains the schematic for this setup. The

Construction Mechanical structure Compressed air comes from air compressor and goes in the proportional valve. Coming out from the proportional valve, there are two branches of air flow (one is compressor air, the other one is exhausted air) which connect to the air cylinder (pneumatic actuator). The pneumatic actuator connects to a cart (the aluminum

Biking around cars can be a frightening thing, and staying visible at night is crucial for your safety. This tutorial will teach you how to make a custom LED Matrix Backpack that is much larger and brighter than traditional rear bike lights. Parts You’ll Need: Individually-addressable RGB LEDs Arduino Pro Mini (or any Arduino, this
LED Matrix Bike Safety Backpack using arduino Continue Reading
Schematic Since the IR Sensor uses a light sensor, the schematic is very similar to that of the light sensor. The only difference is the addition of an IR LED and that the IR detector requires connection to 5V and ground. Breadboard Setup To setup the sensors you will need: 2x IR Detectors 2x IR
