Raspberry Pi - Automation and Scheduling
Which Raspberry Pi GPIO pin mode should be set to control a water pump in an automated watering system?
Which Raspberry Pi GPIO pin mode should be set to control a water pump in an automated watering system?
easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Understand GPIO pin modes
Input mode reads signals; output mode sends signals to devices like pumps.Step 2: Determine correct mode for pump control
To turn pump on/off, GPIO pin must be set as output to send control signals.Final Answer:
Output mode -> Option DQuick Check:
GPIO mode for pump = Output mode [OK]
Quick Trick: Use output mode to control devices like pumps [OK]
Common Mistakes:
MISTAKES- Using input mode which only reads signals
- Confusing PWM with basic output
- Thinking analog mode exists on Raspberry Pi GPIO
