In this video, I will show you how to build a wireless token display system using two ESP32 boards, 4-digit display modules, a keypad, and a buzzer. This system works by using one ESP32 as a client and the other as a server, connected via Wi-Fi. When a number is entered on the client side using the keypad, it is displayed on the local 4-digit display and sent to the server side upon pressing the hashtag button. The server receives the number and displays it on the 4-digit display, while a buzzer activates for 1 second as a confirmation.
Token display systems like these are commonly used in food courts, hospitals, banks, and appointment counters for queue management. Watch the full video to see how you can create your own wireless token system!
