Connect an analog joystick to an Arduino. Read two analog values (x- and y-position) and a switch using a method witch does not hog the processor during the whole ADConversion. The capacitor reduces digital noise on the analog readings. Code static const byte ADC_CHANNEL_JOYSTICK_X = 0; static const byte ADC_CHANNEL_JOYSTICK_Y = 1; static const byte ADC_CHANNEL_MAX = 2; […]
