As from 19th January 2015, the various sketches below "time out" if they don't enter programming mode after 50 attempts. This uses one Arduino to detect the signature, fuses, and bootloader of another ...

For backlighting purpsoe, 5V dc supply is fed to the backlight pins BL1 and BL2 (also labelled as LED+/BL+ and LED-/BL-) through a suitable current limiting resistor (for instance, with a 100-Ohm one) ...

As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...

[Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to send (or receive) serial messages, too. This is a neat idea — kind of a simplified Bus Pirate.

When you launch the Arduino IDE for the first time or when you create a new sketch from the ‘File’ –> ‘New’ menu (Ctrl+N), the editor opens a new sketch template containing skeletons for the functions ...
