Part 1

Circuits

Let’s make our first circuit

Let’s make our first circuit together

Note the LED only works with + connected to the long (bend) led and - to the other one.

Protecting the LED 💡

Woohoo 🥳

And you can measure to check

Part 2

Microcontrollers

Microcontrollers

A microcontroller (MCU for microcontroller unit) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals.

Let’s make a blinking LED together

Think of ‘0’ and ‘GND’ on the MicroBit as the battery you can turn on and off in code

Breadboards are popular for prototyping. When you hover the mouse over it, it will show which holes are connected.

More components - Buzzer

More components - Motion Detector

Project: Burglar Alarm

Breakout Rooms

Create a Burglar Alarm

Use the Motion Sensor to trigger the alarm

Consider

• You only have three input/outputs (0, 1, 2)
• Use the MicroBit buttons to arm/disarm your alarm system
• Use the LED as external alarm light (on or blink)
• Use the Buzzer to scare the burglar off
• Have a way to reset the alarm
