We will blink an LED again, except this time we will move it to to the breadboard. The difference is that we are connecting an external circuit to our microcontroller by giving one of the pins an output signal (much like how everything is run). This is important for two…

Blink, blink. Hello World! (1)

So you have an ULCK set in your hands. Now what? Have you downloaded the Arduino IDE (required for programming) and followed the guide for board definition installation for the ESP8266, the driver installation for the Arduino Nano, or the complete installation procedure for the Digispark? If not please install…
