This workshop aims to teach participants into being confident creating a virtual Arduino circuit using Wokwi as an online simulator for hardware and coding. In addition participants will have an “Open-Eye” on many different aspects of coding, other than apps and software, to create a fun design and activity using Arduino
Projector/Screen, Laptop, Internet Access
Lesson Materials:
After attending this session, participants will gain:
This session depends a lot on discussion and student input and work.
A quick introduction about us and a way to break the Ice with the participant in order to engage with them in indirect way just to make a conversation and then a question to start the session.
Introduction & Icebreaking
1- Introduce yourself and Studio5.
2- ask about Arduino in general.
Presentation :
1- What is Arduino? introduce Wokwi
2- How to signup/login to Wokwi?
3- How to use Wokwi?
4- What are the extra features on Wokwi.
5- Who to create an Arduino based project with Arduino Uno, Buzzer and Potentiometer.
6- Let’s create the Happy Birthday Arduino circuit.
We will start by showing how to access Wokwi.
How to create project.
How to use component.
How to create C loops.
How to create C Arrays
How to manage the Arrays and Tones.
How to handle different song speed using Potentiometer.
How to create the final outcome, Happy Birthday Arduino Circuit (Demo Video)
