Ready-made SD card logging shields for the Arduino typically cost in the range of $15 – $25. This is quite reasonable, but we might save a couple of bucks if we make our own. Not to mention all the fun in building it. Forget about soldering wires to a bare SD card socket. It’s just […]
Communicating with a host computer can allow a simple Arduino-based system to gain access to a wide variety of devices and information. Most people link an Arduino to a host using serial communications across a USB connection with custom code running on the host to send information to the Arduino or receive it in return, […]
We always need to see the temperature and humidity when we sitting in our house to know whether we need to turn on/off AC, heater,cooler,etc. So here we have build this circuit to display temperature and humidity on the 7-segment displays, and we have used DHT22 to bring out the temperatures and humidity and a […]
This project is to construct a musical football. The reason for my project is that I was inspired by a little kid with austim who love sports and music. So what better way to have fun then have a ball that you can play with and create music with. The following steps show how I […]
Introduction: Lighting is an important aspect of visual art. And if the lighting can change with time it can become a significant dimension of the art. This project started with attending a light show and experiencing how the lighting could totally change the color of an object. We began to explore this in lighting fabric […]
This was one of the first programs i wrote for the arduino after having it a few days 🙂 we will be making l.e.d police lights with minimal materials Step 1: You will need. You will need Arduino (or suitable clone) Breadboard 2x 240ohm resistors 1x Clear Red l.e.d 1x Clear Blue l.e.d Some Jumper […]
I knew there were devices that could trigger a camera to fire during a lightning strike, but their circuits were more complicated than I wanted to make. I’m a software guy not a hardware guy so I decided to use an Arduino and that allowed me to write a little code that made the circuit much simpler. Before I […]
This project is a motion activated redstone lamp. It works by using a crumble microcontroller and an ultrasonic distance sensor wired up to a relay. This project is being entered into the minecraft competition and any votes, favorites or comments would be greatly appreciated! Step 1: Minecraft Redstone Having played Minecraft for quite a long […]
I love the idea of the BlinkM (individually addressed RGB leds controlled with 2 pins), but not so much the price (nearly 15 quid each!). Luckily, the hardware is open source and somebody has brought out an alternative firmware (although if you know where to look, you can find the official firmware). This is the […]
Because of the remake of the animation and movie of Space Battleship Yamato, in addition to the attractive design of Bandai model. It make me interest to build this space battleship model again. Bandai not mention its scale, maybe ~1:2500 by estimation. Step 1: Start Design the assemble Sequence and Drill Holes for Those Lighted […]
