🔨 Explore Hardware: Exploring Analog Signals with Arduino

​Discover how robots sense the world around them by working with simple sensors like potentiometers (adjustable knobs) and photoresistors (light sensors). You’ll learn how Arduino uses Analog-to-Digital Conversion (ADC) to turn real-world signals into numbers it can understand. By the end, you’ll be able to map that sensor data to control things like LED brightness or motor speed. No prior experience needed!
