Password locks are relatively common in life. There are various types of locks. The most common ones are in the form of numbers. Generally, you need to enter a few numbers to complete the password. This project uses color to complete the password lock. There are many types of colors, which are more complicated than numbers. Using color cards to set the password and unlock the lock is more difficult to crack, and it is relatively safer.
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.
If you are away from home for a long time on a business trip, the goldfish at home will starve. Therefore, in order to prevent goldfish from starving when the owner is not at home, an automatic feeding robot was designed based on a 4-degree-of-freedom robotic arm and GD32E231. GD32E231 controls the robotic arm by generating PWM. At the same time, it picks up fish food from a fixed place and puts it into the fish tank according to the preset time. Through multiple manual trainings, the robotic arm automatically calculates the feeding based on the manual training data. eating position. At the same time, you can also add some auxiliary functions. You can roughly obtain the internal temperature of GD32E231 and the lighting conditions around the fish tank through the serial port or onboard ADC and photoresistor. You can turn on lighting equipment such as desk lamps when it is dark.
The overall idea of the project is to use the GD32E231 development board as the main control unit, use the LCD5110 display screen and two user buttons as the human-computer interaction module, use the infrared probe for monitoring, and use the AT24C02flash chip to save and record the triggering time of the monitoring alarm, so that Initial implementation of basic intelligent functions.
The home facilities on the RV include: lighting, sofas, seats, air conditioners, TVs, stereos and other electrical appliances. It is inconvenient to set independent switches for each appliance. The smart RV control system solves such problems. The deep learning speech recognition technology of artificial intelligence technology achieved a breakthrough in 2013, and the voice interaction method will occupy an important position for a long time after the technological breakthrough. Large-size touch screens are also the development trend of vehicle-mounted human-computer interaction equipment in recent years. This system uses speech recognition and display human-machine interface (HMI) as human-computer interaction equipment, and users control electrical appliances through voice and touch screen.
This solution is based on the GD32E231 Cortex-M23 core MCU as the main control. The Wi-Fi module uses Essence's ESP8266 and is developed for secondary use. The LCD screen using the SPI interface displays relevant information. The peripheral circuit part uses simple LED lights. Buttons and sensors to complete the demonstration function with the MQTT server.
