The 1K resistors are used for base current limiting, and the 390R resistors limits the operating current of the LED display segments. In the Arduino board, digital outputs from D2 to D8 are used to ...

Arduino DMX. There’s only a single piece of cheap hardware needed to add to an Arduino-compatible design to allow it to handle DMX – just an RS485 transceiver chip. There are many of these around us, ...

Sometimes, you just want to go big. Case in point, Make’s guide to make your gigantic, Jumbotron-esque LED video screen.The project here is powered by ...

[Hlesliebole] wired a 7-segment display to show the current time delay between photos. This can be set on the fly with a potentiometer, so there’s no need to stop and reprogram the Arduino.

To build this DIY buzz wire game, you'd need an Arduino Nano, a 9V battery, two LEDs (red and green), a buzzer, a seven-segment LED display, a shift register for the display, and resistors for the ...

Electronic and Arduino enthusiasts may be interested in a new creation by developer Paul Bartek, who has created an Arduino touchscreen display in the form of the Sunflower Shield. The new ...

WifiDuino has been designed to offer users an open-source Arduino-compatible, wifi-enabled board. Enabling makers and developers to use Arduino IDE (Integrated Development Environment) interface ...
