With this code we seeks to connect and automate the Chem-Ecar 2025 with the goal of developing a more practical vehicle for the following year's competition 🚗.
This code is designed to work with Arduino Uno, a microcontroller board based on AVR technology.
To simplify the circuit, we've employed the built-in input pull-up resistors on Arduino Uno. By enabling the pull-up resistor on digital pin 2, we can detect voltage changes when the pin is grounded, eliminating the need for an external resistor.
Arduino Uno offers two pins specifically designed for interrupt handling: digital pins 2 and 3. These pins allow the microcontroller to react to external events without constantly polling the pins, improving efficiency and responsiveness.
For this project, we've utilized digital pin 2 to trigger an interrupt when the voltage level changes, enabling precise control of the servo valve.
The servo valve design is by red5alex and can be found on Printables I used this design and it worked great.
