A digital office door sign system that allows users to display custom messages on a sign outside their office. The messages are managed through a user-friendly web app hosted on a Raspberry Pi. The system sends these messages wirelessly to a display module using WiFi or Bluetooth. This solution combines embedded systems with web technologies to provide an efficient and customizable communication tool for professional environments.
I designed and implemented the entire system, which involved several key components. I programmed the STM32 microcontroller to process messages and control the display, ensuring seamless operation. Additionally, I configured the ESP32 for wireless communication, enabling reliable connectivity. Finally, I developed a web app dashboard, which was hosted on a Raspberry Pi to provide a user-friendly interface for monitoring and control.
System features include:
