I literally had my Android phone controlling a Arduino Mega 2560 in just minutes. If that’s the case then I guess it depends what library is being used to write data to the LCD, but there’s a good chance that every time he prints data to the physical LCD he could also write data to the Blynk LCD widget. It implements a streaming connection protocol, allowing for low-latency and bi-directional communication. PeteKnight March 10, 2023, 4:10pm 4. Please help me with highlighted code what should i do to get the code from LCD widget to 5110 lcd screen or there any simple method to transfer from blynk First off, I love Blynk and this Forum!
