Inspiration
Our inspiration in making this project was to engineer a device that harbored creativity. The artist would be able to express themselves and make their living environment more personalized.
What it does
This project utilizes the ESP32 microcontroller to receive drawing data via Bluetooth and display it on an 800x480 7.5 inch e-paper screen. The ESP32 communicates with a Bluetooth device (laptop) using Bluetooth Serial (SPP), allowing users to send drawing data. The received data is then processed and displayed on the Waveshare e-paper screen via SPI communication. Hang it on your wall as your own personal art piece.
How we built it
Key Components: ESP32 Microcontroller - the main controller responsible for managing Bluetooth communication and display updates Waveshare 7.5-inch E-Paper Display (800x480) - the display device that shows the received drawings. The display is updated using the GXEPD2 library, which controls the display's pixel data Bluetooth Serial (SPP) - Used for wireless communication between the ESP32 and a Bluetooth-enabled device, such as a laptop SPI Communication - the communication protocol used to send data between the ESP32 and the e-paper display, ensuring fast and reliable data transfer for drawing updates
Challenges we ran into
Some challenges we ran into were mostly on the hardware side. Unfortunately, despite having all the components of the project working, our Waveshare e-paper screen was damaged. Due to this, we were unable to have final product of the project.
Accomplishments that we're proud of
What we learned
We learned to make sure our hardware is working before taking on such a task that ultimately lead to disappointment. However, this is a learning curve and we will purchase a new screen and finish the project.
What's next for DrawFrame
