HERO Board Basics

Platform reference: pins, boards, IDE, and upload workflow

• Analog Input: analogRead — Read continuous values from sensors and potentiometers. The ADC converts voltages (0-5V) into numbers (0-1023) for your code.
• Digital I/O: pinMode, digitalRead, digitalWrite — The three core digital functions. Control LEDs, read buttons, and interface with on/off components using HIGH and LOW signals.
• PWM: Pulse Width Modulation — Simulate analog output using digital pins. Control LED brightness, motor speed, and servo positions with analogWrite().
• Serial Monitor — Your debugging lifeline. Print messages from your Arduino to the computer screen to see what your code is doing in real time.
