Which Raspberry Pi UART pins are commonly used to connect to an Arduino for serial communication?
Which Raspberry Pi UART pins are commonly used to connect to an Arduino for serial communication?
easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify UART pins on Raspberry Pi
GPIO14 is UART TX (transmit), GPIO15 is UART RX (receive).Step 2: Confirm pins used for serial communication
These pins connect directly to Arduino RX and TX for UART communication.Final Answer:
GPIO14 (TX) and GPIO15 (RX) -> Option BQuick Check:
UART pins = GPIO14 and GPIO15 [OK]
Quick Trick: Use GPIO14 and GPIO15 for UART TX and RX on Raspberry Pi [OK]
Common Mistakes:
MISTAKES- Confusing I2C pins (GPIO2, GPIO3) with UART
- Using random GPIO pins
- Swapping TX and RX pins
