Smart ordering display based on arduino

Overview

1. The engineering principle
is based on the arduino UNO development board, which integrates the DS1302 clock module, HC-SR501 infrared sensing module, OLED display module, LD3320 speech recognition module, and LED display lights to form an intelligent ordering display in the canteen.
2. Function description
1. After power-on, the colorful LED lights up, and the display screen displays the prompt "Welcome" 2. The display screen displays the current clock time 3. When it detects someone coming, the two-color LED turns green, and the display screen displays "Please" "You are ordering" prompt 4. When the guest says the name of the relevant food, the display will display the corresponding price 5. When the guest finishes ordering and issues the "order complete" command, the display will display the total price
