I tried to use the Senbazuru as the tactile output to create the rotational motion. And the red LED is another outputs. The rotation rate of Senbazuru and the brightness of the LED can be adjusted by the potentiometer.

int potVal = 0;
int motorCtrlVal = 0;

void setup() {

pinMode(motorPin, OUTPUT);

void loop() {
potVal = analogRead(potPin);
Serial.print("potVal: ");Serial.println(potVal);
motorCtrlVal = map(potVal, 0, 1024, 0, 255);

General Idea

Using LEGO pieces as the tangible input and research the output.

Use Case - enabling modular construction blocks to be both infinitely reusable and idea-preserving.

There is a tension in building with LEGO (or other construction…
