Python Tutorials – பாடம் 3 – Use A Buzzer Module Using Raspberry Pi Pico

Raspberry Pi Pico வை பயன்படுத்தி Buzzer (ஒலிப்பான்) ஐ கட்டுபடுத்துவது

Required Components

1. Buzzer module-1 no
2. Raspberry Pi Pico-1 no
3. Connecting wires-1 set

Circuit

Steps

1. நாம் பயன்படுத்தும் உபகரணங்கள் சரியாக வேலை செய்கிறதா என்பதை உறுதி செய்து கொள்ளவும்.
2. Buzzer (ஒலிப்பான்) ஐ Raspberry Pi Pico GP15உடன் இணைக்க வேண்டும்.
3. Buzzer (ஒலிப்பான்) Ground உடன் Raspberry Pi Pico Ground ஐ இணைக்க வேண்டும்.
4. Python program ஐ சரி பார்க்க வேண்டும்.
5. மின்சுற்றை சரி பார்க்க வேண்டும்.
6. Python program ஐ ரன் செய்ய வேண்டும்.
