Enhance your project with the Ultrasonic Distance Sensor (RCWL-1601). Pin and software compatible with the HC-SR04 sensor, it uses echolocation to detect objects within a range of 2 to 450 cm. Now compatible with both 3.3V and 5V power supplies.

Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a buzzer.

The oscillator is the main sound source in the Synth Kit and is capable of creating audio tones that will be used in almost every sound experiment you create. It features a "pitch" knob to adjust its output tone and a "tune" dial for adjusting the tuning when using with the keyboard. It also features a mode switch that selects between "square" and "saw" waveforms. The "square" waveform has a rich, powerful character, and the "saw" waveform has a more mellow, rounder character. [You'll often use it after the Keyboard or Micro Sequencer Bits modules, but you can have lots of fun by just twisting the pitch knob and "sweeping" through all the frequencies from high to low pitches.]
