AC control timer

Project description

How to Build a 4-Channel AC Timer Switch with W5500 and Raspberry Pi Pico? Summary This project implements a programmable 4-channel AC timer switch using Raspberry Pi Pico, WIZnet W5500 Ethernet, DS3231 RTC, SSD1306 OLED, and a joystick interface. The W5500 is used for NTP-based network time synchronization, allowing the controller to maintain accurate schedules while the DS3231 provides backup timekeeping during network outages. What the Project Does The system controls four independent AC outputs through photo-triac and triac circuits. The hardware consists of: Raspberry Pi Pico WIZnet…
