Arduino Workshop for the Curious

From Electromagnetic Field

This is a workshop for people who have never used an Arduino before, but are curious and would like to spend a couple of hours exploring this fascinating tool.

It helps if you have some programming experience, in any programming language, so that you are familiar with the idea of variables, functions, if-statements, etc. You can learn about them before the lesson by working through at least lessons 1-4 of this online Javascript course before coming on this workshop.

I hope to have around 10 people in this workshop, and want it to be fairly self-paced so that students can progress at their own rate. I'll guide the class's direction but also try to pair more advanced students up with the less able students in order to spread teaching ability around.


How to Book a Place

If you're interested in coming, please email me at (without the ABC) . Try to include:

  • Your name
  • Whether you want to buy/borrow equipment or can bring your own.
  • A sentence about your experience with programming/Arduinos
  • Whether you're interested in a Sunday night workshop or not

There's a limited number of places, so if it's oversubscribed you might not get an Arduino, or have to share.


What You'll Make

We are going to incrementally build our own morse code communication devices. They will translate text into morse code, which will then be emitted using a speaker or an LED. Another Arduino will then listen to/detect your morse code and decode it back into text. After this lots of weird and wonderful things can be done with communicating Arduinos - your imagination is the only limit!

In order to make this easier, the workshop will be incremental in nature. Our morse code gadgets will be designed and built in the following stages:

(1) Blinking LED machine
  • the structure of an Arduino program
  • integer variables
  • calling functions
  • digital outputs
  • using LEDs
(2) Two Character LED-Based Morse Code Emitter
  • creating functions
  • string variables
  • if statements
(3) (Optional) Two Character Speaker-Based Morse Code Emitter
  • PWM and digital waveforms
  • handling inductive loads
(4) Two Character Light-Based Morse Code Detector
  • analog inputs
  • more complex if statement conditions
(5) Morse Code Decoder
  • time measurement
(6) Demo Challenge
  • anything you're interested in!
  • arrays and ASCII?

What You'll Need

Component For Sale

You're welcome to bring your own components, but if you don't have any then I'll bring some that you can buy from me. The course assumes all students have at least the components of the Arduino Starter Kit.

Component Link Price
Arduino Starter Kit £26.70
Servo £5.00
Sharp IR Sensor £10.50
Potentiometer x1 £1.00

Arduino Starter Kit

This starter kit, or a set of equivalent components, is recommended for the course (especially the red components). You can buy it from me at the workshop, but arrive early because I only have 10 of them!
