For-fun experiment with an Arduino UNO, where a passive piezo-buzzer’s pitch is controlled by an ultrasonic sensor (HC-SR04). The whole idea of this “pseudo-theremin” is to obtain the proximity to the ...
In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...
Arduino version of an Atari arcade memory game called Touch Me, using four LEDs, four pushbutton switches, and a piezo buzzer.
