I am reading "Temperature" value from BMP180 with Arduino Mega. Basically what i need to do is sending these sensor values to Nextion monitor. Main purpose of my project is showing multiple sensors' value on Nextion monitor. I am ok with Nextion Editor but not with the Arduino Mega. How can i send these values ?
Perhaps your situation isn't so far off when dealing with the BMP180 as a DHT11.
Please refer to John Frankforther's thread Writing data to text box
You stated you are not ok with the Arduino Mega. This is going to take some digging in, but will be a needed step, which is beyond the scope of the forum. The ITEADLIB Arduino Library (configured for Mega) can be located here.
