1. Mia is trying to build a robot that turns on an LED when it detects motion using a PIR sensor.
After connecting everything, she finds the LED doesn’t light up when motion is detected. What
troubleshooting steps should Mia take to identify and fix the issue?
2. Liam wants to create a system where a buzzer sounds when the soil is too dry. He connects a soil
moisture sensor and a buzzer to the Brain Module, but the buzzer never sounds. What could Liam
check in his setup to ensure that the buzzer activates correctly when the soil moisture is low?
