An online learning platform that all national maker education teachers are paying attention to The electronic piano made with Arduino UNO can play the notes “do re mi fa so la ti” in order. To enhance the performance by an octave, a pitch-bend button is placed on the far right of the piano. Additionally, for … Read more
❝ The ESP32 is something many people may have heard of or used. If you have previously used an Arduino development board, you might have come across it as well. The ESP32 refers to a series of chips and modules produced by Shanghai Espressif Systems, rather than a specific chip, which is something to note. … Read more
I’m sharing my experience of transforming a USB socket into a WiFi socket. I spent three days reorganizing and testing the source code, and I made some improvements to the app. I believe that with my source code and app, you too can have your own WiFi socket. Required Components One socket (I used a … Read more
