LCD Shifter for Arduino

The original idea was to create a library that simplify the use of IC 74HC595 between Arduino and other hardware. In this Instructable I will share this to you using as example the control of a 16x2 LCD. The example will show on the LCD the seconds that has passed since Arduino was restarted. I hope it will be useful to you. Step 1: Place the Library under Arduino Folder I've named the library "ShiftOut". I ...

Webcam Controller

A ideia deste projecto surgiu-me quando um dia estava a aceder remotamente ao meu PC para consultar uns trabalhos e imaginei que desta forma e ligando uma webcam poderia ver o que os meus gatos andariam a fazer quando sozinhos. No entanto precisava de algo mais pois a webcam pousada no topo do monitor não iría dar uma visão geral da divisão. Foi nessa altura que me lembrei de construir um circuito que permi ...

Arduino 7 Segment LED Display and Counter – Tutorial #8

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can be powered from a standard 9V PP3/6F22 battery, or from any suitable Arduino power adaptor.The seven segment display is infact a very simple d ...

Arduino-controlled blinds: a tutorial

Have you ever wanted a smart home that can automatically adjusts the blinds for you? If so, this project is for you. In this instructable, the author describes his approach to “smart blinds”, by using an Arduino board, an ethernet shield, a motor shield and a couple of sensors. By means of a simple web-based GUI, the user can manually open and close the blinds, or he/she can setup both temperature and brigh ...

Temperature Sensor DS18B20

Electronic Brick, Waterproof and other Versions NOTE: There are different-appearing versions but they work the same. This is an electronic thermometer which has high accuracy over a wide range (accurate to ±0.5°C over the range of -10°C to +85°C) (Workable from -55°C to +125°C). You can locate these thermometer chips up to 100M away from your Arduino. Shorter cables can be just 2 wires. NOTE: There must be ...

Say stop to unwanted „visitors“

EMI mains filters Schurter combined with an input AC connector will stop interference there, where it´s the most efficient - at the input. To be more precise, usually it´s the best to eliminate interference (EMI) already at a source of interference itself. But because there are a lot of disturbance sources in a common 230V mains, the only reliable possibility how to protect our device is to equip it with a ...

Playfield :: Hardware :: Flippers

If you are contemplating building your own machine, then you probably already know a good bit about how pinball machines work. It’s basically series of electro-mechanical events where a steel ball activates a switch, which in turn fires a solenoid that drives a mechanism, sending the ball off in some other direction where it most likely hits another switch, and so on and so on… The Flippers are the only rea ...

StrobeDuino – Computer-controlled RGB strobe/lamp

After experimenting with Arduino and Processing serial communication i wanted to do something cool. I had some RGB LEDs lying around so i thought about making something with them. I ended up with a strobe/lamp controlled by a Processing sketch that receives the commands from a Hercules DJ Control Steel MIDI controller. It uses 2 3W RGB LEDs, 6 constant current drivers to ensure every LED gets the proper cur ...

Arduino Air Cap-Sense Piano

I recently got my shipment of 10 buzzers I ordered about a month ago, so as soon as I got them I was eager to make something fun with them, so I looked around a bit and searched for what to do with them, and by spending some time on www.arduino,cc and posting lots of questions on the forums, I figured out what I am going to make. I decided to make an air piano which is based upon cap-sense and the arduino. ...
