Ciseco's LED display: With the LED display (http://shop.ciseco.co.uk), which is available in white or red, 126 LEDs can be used to display e.g. share prices or weather information in real time. The LEDs are controlled by a built-in ATMega328p processor, so that the Pi processor is relieved of this task and can concentrate its computing power on the actual application. Of course, bar graphs and other simple graphics can also be displayed. The Pi Lite board is simply connected to the Pi's GPIO pins and programmed using Python code. The display costs 19 pounds.
