Ornamental fish tank controller

The ornamental fish tank controller is studied, developed and verified based on the Arm® Cortex®-M23 core GD32E231C-START evaluation board provided by GigaDevice for this competition. Finally, the GD32E231C8T6 microcontroller chip donated by GigaDevice was used to realize the status control of the fish tank circulating water pump, the three-stage brightness control of the LED lighting, and the granular bait feeding control using the 315MHz remote control receiving and transmitting device and other related peripheral equipment. As well as an ornamental fish tank controller with functions such as water temperature collection and digital tube display.

Automatic doorbell with object detection

Every house has a doorbell. When a visitor arrives at a home, he looks for the doorbell switch and rings it to let us know his presence. What if a person coming to your home cannot find the doorbell, or the person is too short to reach the doorbell? The object detection circuit installation below is for reference. The circuit will automatically sense the presence of a person and ring the doorbell.
