So you just bought this Arduino kit or Arduino-clone kit. You spent hours inserting parts and soldering components. You connect everything up and turn it on and stare at the little LED. You wait a second and nothing happens. You wait a minute and still nothing happens. So what do you do? Well, I have […]
This instructable primarily shows how to control the charging voltage from a solar panel to an energy storage device (capacitors in this case). I showed how to construct the light previously http://www.instructables.com/id/Human-Powered-Light-from-my-book-Doable-Renewab/ Step 1: This solar panel can produce up to 18 volts, but my capacitor bank should never receive more than 15 volts. I […]
Hi. This Instructable will guide you through the process of wirelessly programming your Arduino using two XBees. I just finished designing a wireless EEG system with the XBee modules, so I’ve become quite fluent in their programming and have just now been able to accomplish this. It still amazes me how difficult it has been to try to wirelessly […]
Hello! In this Instructable i will teach you how to control a servo using a Photocell. This is very simple and good for beginners. Step 1: Materials 1 x Photocell 1 x 10k Resistor 1 x Arduino 1x Breadboard 1x Servo and some jumpers Step 2: Wiring it up Wire everything following the schematic below. […]
The project A polar plotter is a plotter with a rotating, extendable arm. Its characteristics differ greatly from those of a traditional plotter, which in most areas have a superior design. You could say the polar plotter is more portable or something, but mainly I made this one because it was more of a challenge. […]
This is basic for your arduino projects, input switch read from digital input. When ever switch pressed, LED will turn on. Instruction; 1) Connect cathode lead of LED (shorter lead) to ground pin and anode lead of LED (longer lead) to pin 13. 2) Add switch to breadboard, connect one of the switch […]
The String comparison operators, ==, !=,>, < ,>=, <= , and the functionsequals() and equalsIgoreCase() allow you to make alphabetic comparisons between Strings. They’re useful for sorting and alphabetizing, among other things. The operator == and the function equals() perform identically. It’s just a matter of which you prefer. So if (stringOne.equals(stringTwo)) { [Get Code] […]
This sketch shows you how to read information from the Esplora’s joystick and use it to control the movement of the cursor on your computer. You’re making your Esplora into a mouse! This sketch will take over the mouse movement of your computer. If you lose control of your cursor do the following : unplug […]
In this instructable the main focus lies on the software which I’ve created – not so much on the hardware side. You needn’t to use a high- power led for this, you can use every RGB- LED you like. The “High Power RGB LED Moodlamp” is a high power rgb led lamp which can be […]
Project Gado is an initiative which aims to create an open-source archival scanning robot which small archives can purchase for $500 and use to autonomously scan their photographic collections. This talk presents the Gado 2, a prototype
