This project is a solenoid control board designed to efficiently manage up to 8 solenoids using a compact and scalable architecture. The system is based on a shift register that receives serial data through 3 GPIO pins of a microcontroller. These GPIOs are configured to handle the data, clock, and latch signals required to control the shift register, ensuring precise and synchronized operation of the solenoids. The use of a shift register minimizes GPIO usage while enabling reliable control of multiple solenoids, making this design ideal for applications where pin availability is limited. The board may include features such as overcurrent protection, status indicators, and expandable daisy-chaining for controlling additional solenoids. This solution is suited for automation, robotics, or other systems requiring efficient and scalable solenoid control.
