It is nothing new for TDA 7439. A lot of people did that, and I am inspired by them. That was my 2nd project on Arduino and TDA 7439 with LCD (16x2). The Dot Matrix LCD was not very impressive for me; for that reason, I just tried to make it colourful with a large display. As a new user on Arduino, it was quite challenging for me. This is my 3rd project on Arduino Nano with TFT ILI9341 display, but I faced a problem after 70% of the code was written. The flash memory of the Nano exceeded the limit, and then I shifted to ESP32. It is my 1st experience on ESP32. I was very confused to choose the ESP board because there are hundreds of types of ESP32 boards! Then I choose the ESP32 WROOM devkit with 2 reasons: 1. I need more flash memory than Arduino Nano. Nano's memory was not enough. And the 2nd reason is that the ESP32 is quite cheap and available in our local market. other hand capacitive touch features available in ESP32. I configure the switching in 3 different ways: rotary encoder, tact switch, and touch switch. The TFT screen is not as good as a mobile screen but much better looking than an LCD. I've used the Sony TV [RM-ED054] remote control, which is also very cheap and available. I have a plan to control the system over Wi-Fi but am facing the problem that "WIFI manager" is conflating with the eTFT library [so far, I guess]! I need to dig more about this issue...
