SYNTHESIS WORKBENCH
Shape the sound
in your head.
Choose a destination, tune the building blocks, and get a practical patch recipe you can dial into any synth.

Understand the signal
A synth is a chain of small decisions. Follow the signal from raw tone to finished gesture, then make one change at a time.

Assemble a physical voice
Build this beginner-friendly mono synth voice in small, testable stages. It uses a 555 oscillator, a simple tone filter, and an LM386 amplifier module.
Stay safeUse an isolated 5V USB supply only. Disconnect power before rewiring, check polarity, and never connect this breadboard to mains voltage.

NE555 pin map
Use the notch as your orientation mark. Pin numbers run down the left side, then back up the right.
| Pin | Name | Connect to |
|---|---|---|
| 1 | GND | Ground rail |
| 2 | TRIGGER | Timing node (2 + 6) |
| 3 | OUTPUT | 4.7kΩ filter input |
| 4 | RESET | +5V rail |
| 5 | CONTROL | 10nF to GND |
| 6 | THRESHOLD | Timing node (2 + 6) |
| 7 | DISCHARGE | 1kΩ + pitch pot network |
| 8 | VCC | +5V rail |

Build in this order
Finish and inspect one net before moving to the next. This makes faults much easier to find.
01Power rails: +5V and GND
02Timer supply and reset pins
03Timing resistors, pot, and capacitor
04Output filter and coupling capacitor
05Amplifier, volume, and speaker
Meter checkWith power disconnected, use continuity mode to confirm each shared node. With power connected, measure between +5V and GND before inserting the speaker.
