SynthCard

Synth Card for Adam Wonak

This synthcard is a circuit inspired by Hagiwo's SyncLFO and Bezier Curve, and the Modulove MVMNT. I chose this design because of the seemingly endless creative firmware scripts I have written for the Modulove Sync LFO, so I wanted to make a business card to highlight this circuit design with some fun tweaks.

This is an iteration of the SynthCard.com community from Benjie Jiao.

Pinout

Code Example

The most basic program we can write for the Synth Card is a Blink program. Using the pin guide above, we can see the digital output is D10 which has an LED connected to the circuit. We can use this pin to blink the LED.

#define CV_OUT 10  // CV Output with LED

void setup() {
  pinMode(CV_OUT, OUTPUT);
}

void loop() {
  digitalWrite(CV_OUT, HIGH);
  delay(500);
  digitalWrite(CV_OUT, LOW);
  delay(500);
}

To test out all of the inputs, outputs, and LEDs, you can flash the HardwareTest script.
