I made this Arduino project ... [4] = 1; } break; The array itsONled[] = {0,0,0,0} is used to set the initial state of LEDs (in our case OFF) and has number of leds + 1 more zeros, so if you add 2 ...

Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer. We like how [newsonator] wired up the LEDs to the Arduino by ...

Nobody doubts the utility of the Arduino Nano and its many clones ... reset button, built-in LEDs, 5 V regulator, and preloaded bootloader. Its big extra feature is the 350-kilosamples-per ...
