You’ve made a circuit! Experiment with adding additional LEDs to the circuit, connecting them with more small pieces of wire. You might want to sketch out the circuit variations that work to guide you ...

I had the idea of building this Arduino icicle lights project during the making of the light dimmer circuit and the result can be seen below. Is not a complicated project so it can be done easily by ...

As you can see from that sketch and the circuit diagram, the LED is connected to the digital pin 13 of the Arduino. Once you verify (compile) the sketch and upload it to the Arduino board, you should ...

There are many circuit diagrams available online for building an Arduino on a protoboard, but after an extensive research and after some little tweaks, I’ve come up with this tried and tested circuit.
