Turn your Arduino into a 4 voice wavetable synth
This instructable will show you how to make a simple sequencer that plays a little melody. You can hear how it sounds here:
It is up to you to modify the code to do many other things. Possible examples could be a midi controlled synth (sample code included), it could be a strange noise machine like this one:
Or you could detect touch and convert it into sound patterns:
Step 1: Parts
- Arduino board
- BreadBoard
- Wires
- 2.2k Resistor
- 100n Capacitor
- 100u Capacitor
- Jack where left and right channel has one wire and one wire to ground
- A pair of computer speakers
Don’t worry if you don’t have the exact values. It will probably work, but might be with lower sound quality. The Arduino is not powerful enough to drive a pair of headphones so you will need some kind of preamp for that – e.g. a headphone preamp like this one.
Step 2: Add the components to your breadboard
Step 3: Connect to the Arduino board
Step 4: Connect to the speakers
