In this tutorial learn how to make your own backlit-LCD Arduino shield. Let’s see how simple it is to make your own Arduino LCD shield. Sure – you can just buy one, but where’s the fun in that? Getting Started Our LCD is a two line, sixteen character backlit LCD. It has a typical HD44780-compatible […]
This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics […]
This example shows how to play notes on the buzzer mounted on the Arduino Esplora. Buzzers can generate different audio signals in audible frequency ranges. A note is an audio signal at a specific frequency. If you know the frequency of the notes you want to play, you can start to compose a melody. In […]
Let’s be honest for a moment, doesn’t everyone want a dress that lights up at your very whim? No? Alright, well I do. It’s pretty straightforward, though the programming gets a wee bit tricky. So pick up your pencil, sketch out a design and then we’ll talk parts.Here Step 1: Material Step 2: Schematics Before jumping […]
This display is based on an 8×8 RGB LED Matrix. For testing purposes it was connected to a standard Arduino board (Diecimila) using 4 shift registers. After getting it to work I permatized it on a fabbed PCB. The shift registers are 8-bit wide and are easily interfaced with the SPI protocol. Pulse width modulation […]
Who wants grinning faces and candles when you can have an interactive pumpkin this Halloween? Play your favorite block-stacking game on an 8×16 grid carved into the face of the gourd, lit by LEDs and using the stem as a controller. This is a moderately advanced project and requires experience soldering and programming in the […]
I love to integrate devices which are not supposed to be integrated and this guide shows you how you can control an Android mobile using Apple’s Remote. (Who said Apple devices work only with Apple products 😉 ) Also this is my entry to the Sparkfun microcontroller context. If you like this guide, please do […]
I’ve bought recently some cheap dual axis magnetic sensors at SureElectronics (http://www.sureelectronics.net/goods.php?id=944), I’ve tried first to use them as straight compass. Annoying problem : it’s impossible to accurately compensate the tilt of the sensor without using a gyro sensor. On the other end, if you stay on the same horizontal plan, the measures are pretty accurate even […]
This example shows you how to make repeated HTTP requests using an Ethernet shield. This example uses DNS, by assigning the Ethernet client with a MAC address, IP address, and DNS address. It connects to http://www.arduino.cc/latest.txt. The conent of the page is viewable through your Arduino’s serial window. Circuit The Ethernet shield allows you to […]
This ible is for the building of my small, almost matchbox size, arduino compatable board. As seen in this ible.. http://www.instructables.com/id/Pocket-Ardiuno-kit/ I experemented with the one in this ible to see how it can be impreoved, but the consept is the same and so is the build to a degree. Origonally made as a pocket […]
