Playground

A sandbox for the interactive tools used across the courses.

Robotic arm: joint control

Drag the sliders to move each joint. The code on the right updates live. Drag the model to orbit.

#include <Servo.h>

Servo base, shoulder, elbow;

void setup() {
  base.attach(9);
  shoulder.attach(10);
  elbow.attach(11);
}

void loop() {
  base.write(40);
  shoulder.write(60);
  elbow.write(110);
}

Virtual Arduino: Blink

Change the delay and press Run to watch the pin toggle.

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(500);
  digitalWrite(13, LOW);
  delay(500);
}

Python in the browser

A real Python interpreter running locally. Change the numbers and run it. The first run downloads the runtime (about 10 MB).
