DIY Arduino Synth – 3-Step Sequencer Tutorial

Components: 1x Arduino (Uno, Mega, or Nano – whichever you prefer) 4x Potentiometers (the value isn’t important) 3x LEDs (to show the active step) 3x Resistors (I use 230Ω, for the LEDs) 1x Small Breadboard (for the extra potentiometer) 1x Regular Breadboard (for the main circuit) Jumper wires (male-to-male) Optional: Piezo speaker or small audio jack (connected to pin 9 for sound output) ----------- //Code int speed; int freq1; int freq2; int freq3; void setup() { //LED pinMode(5, OUTPUT); pinMode(6, OUTPUT); pinMode(7, OUTPUT); } void loop() { //freq 1-3 freq1 = map(analogRead(A0), 0, 1023, 30, 800); freq2 = map(analogRead(A1), 0, 1023, 30, 800); freq3 = map(analogRead(A2), 0, 1023, 30, 800); //bpm speed = map(analogRead(A3), 0, 1023, 10, 1000); //1st digitalWrite(7, HIGH); tone(9,freq3); delay(speed); digitalWrite(7, LOW); //2nd digitalWrite(6, HIGH); tone(9,freq2); delay(speed); digitalWrite(6, LOW); //3rd digitalWrite(5, HIGH); tone(9,freq1); delay(speed); digitalWrite(5, LOW); }
