Introduction

In this program we will:

• Session 1 — Learn about microcontrollers, and design and simulate a basic microcontroller circuit.
• Session 2 — Wire up your circuit and write the code to control it.
• Session 3 — Get to grips with breadboards and the common code you'll use.
• Session 4 — Move your circuit from the Wokwi simulation to a real breadboard.
• Session 5 — Turn your breadboard circuit into a PCB in EasyEDA.
• Afterwards — Export your board files and hand them to your leader, who orders the real thing.
