Color mixer using the Lilly T-Display-S3
This project uses a LilyGo T-Display-S3 to mix three colours (red, green, blue) showing the resulting colour. Both the input colours and the resulting colour are showned both on the TFT display as well as on an RGB LED.
This project was used to demo to primary school childreen (ages 6-10) that light is made of different colors and that by combining different primary colors you can get all colors.
