The top portion of theDemonstrator is an LED sequencer driven by an Arduino Nano (sold separately). The variable resistor and push-button allow you to control the speed and mode of the LED sequencer.
The bottom portion of theDemonstrator is an LED sequencer driven by a 555 timer IC and a 4017 decade counter IC. The variable resistor allows you to control the speed of the LED sequencer.
We’ve also created a 3D printable display stand. You can print your own*, or add one to your order. (Mounting screws are included when you purchase the stand from us.)
What is an Arduino Nano?
The Arduino Nano is a special kind of computer called a microcontroller. Microcontrollers allow you to control electronics and interact with the outside world through the use of a computer program. The Nano is designed to plug directly into a prototyping board.
The programs for Arduino microcontrollers are called “sketches”. When you purchase an Arduino Nano as part of your theDemonstrator kit, it comes pre-loaded with the sketch needed to control the top portion of your kit. Over time, you can learn how to write your own sketches in order to change the behavior of your kit.
Looking for theDemonstrator sketch to upload to your Arduino NANO? It’s available here.
Note: You’ll need a soldering iron and a few other tools.
