Passo 1: Prepare-se
O que é?
Complete um circuito elétrico com seu corpo, os seus amigos e seu BBC micro:bit.
Este projeto é desenvolvido em parceria com a White Rose Science para professores de ciências e permite que os estudantes entendam como a energia pode ser transferida por circuitos elétricos, e o tipo de materiais condutores. Os alunos também podem aprender sobre como usar sequência, seleção e repetição em programas de computador e várias formas de entrada e saída.
Este vídeo explica como o projeto funciona e como fazer o experimento.
Como funciona:
- Two crocodile clip leads are attached to the micro:bit’s ground pin and pin 1.
- You hold the other ends of the leads with both hands to allow an electrical current to flow through you, or do the same with a group of friends holding hands.
- When the circuit is complete, a stick figure appears on the micro:bit’s LED display and a sound plays.
Itens necessários:
- Um micro:bit;
- um conjunto de baterias
- Dois cabos garra jacaré.
Step 2: Investigate
- Download the hex file and put the code onto your micro:bit. You do not need to write the code for this project yourself to do the experiment, but if you are interested in coding it, visit the Step 3: Code it section below.
- Attach a battery pack to the micro:bit.
- Attach two crocodile clip leads to the micro:bit’s ground pin and pin 1.
- Hold the other ends of the leads in each of your hands to form a circuit or hold hands in a circle with your friends. Break the circle at one point. One person should hold the end of the crocodile clip lead attached to pin 1 and another person should hold the end of the lead attached to the ground pin, to form a large circuit.
- When an electrical circuit is formed, a stick figure appears on the micro:bit’s LED display and a sound plays. Otherwise, the LED display clears, and no sound plays.
