Projecte Final de curs
Com a projecte de final de curs, hem fet un altaveu que funciona amb un microcontrolador.
Materials
- Microcontrolador Xiao Samd21
- Altaveu
- Transistor BC517
- Resistencia de 5kΩ i 100Ω
- Cables
Cablejat
Per el moment, posarem el cablejat en una protoboard per fer-ho mes facil d'arreclar si passa alguna cosa.
