easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Understand the role of the I2C backpack
The I2C backpack simplifies wiring by handling the LCD data pins internally.Step 2: Identify which pins are not needed externally
Because the backpack controls the 16 data pins, you do not connect them directly to the Raspberry Pi.Final Answer:
All 16 data pins of the LCD are not required to be connected directly -> Option BQuick Check:
Direct data pins connection = Not needed [OK]
Quick Trick: I2C backpack handles data pins internally, no direct connection needed [OK]
