Arduino

An Arduino extension for Xcratch

This extension adds blocks to interact with Arduino boards connected via USB, allowing you to read sensor values and control actuators directly from Xcratch projects.

✨ What You Can Do With This Extension

• Read Analog Inputs: Get values from analog sensors connected to pins A0-A5.
• Read Digital Inputs: Detect if a digital pin is HIGH or LOW.
• Control Digital Outputs: Set digital pins HIGH or LOW to control LEDs, relays, etc.
• Set Input Bias: Configure digital input pins with internal pull-up resistors.
• Control PWM Outputs: Set the duty cycle of PWM pins to control motor speed or LED brightness.
• Control Servo Motors: Set the angle of standard servo motors connected to digital pins.
