The point was to learn how to take the most basic circuit connected to an active or passive buzzer and generate musical notes by toggling the circuit HIGH/LOW, and then see how effectively chords ...

5. Build your own Mars Rover Robot using Arduino: This cool looking Arduino Project presents the construction of an Arduino-based Mars rover, emphasizing design, components, and assembly.It highlights ...

I will try to include a better circuit diagram, but for now: Connect the negative of the buzzer to ground and the positive of the buzzer to pin A0. Connect the shorter legs of the LEDs to ground, via ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got ...
