In this how-to article, learn how to build a remote-operated audio oscillator using littleBits. Once it's built, you can view the electrical signals from the oscillator bit using an oscilloscope and wire a piezo speaker-horn to your remote-operated audio oscillator using a littleBits proto module.

Subcircuit Block Description

For the initial project, there are seven littleBits mini-PCB modules required to build the remote-operated audio oscillator. The seven mini-PCB modules consist of:

a power bit,



a remote trigger bit,



a latch bit,



an oscillator bit,



a protoboard,



an LED bargraph bit,



a synth speaker bit.



Figure 1 shows a block diagram of the interconnected bits you need to build a remote-operated audio oscillator.
