To design the GUI, you use the Nextion Editor, in which you can add buttons, gauges, progress bars, text labels, and more to the user interface in an easy way. We have the 2.8” Nextion display basic model, that is shown in the following figure. Getting a Nextion Display You can gra...
The RDA5807 device can work safaty from 2.7 to 3.3V. Be aware that some Arduino board oparates with 5V instead of 3.3V (for example: Arduino Uno and Arduino Nano). A wrong setup can make the system unstable or damage the RDA5807 device. Preferably use an Arduino or other boards like ...
turn a 12V lamp on when you send an SMS to the Arduino with the text “ON” turn a 12V lamp off when you send an SMS to the Arduino with the text “OFF” you can request the lamp state by sending an SMS to the Arduino with the text “STATE”, the Arduino should reply back wit...
nextion as following “tempV.val=22”. So the variable name, then “.val”, then the value, let’s say 22. The first two lines of the code do that, and in order the Nextion display to accept this command or actually any command we need to send the three unique “write”...
“smart” LCD display such as the Nextion devices from ITEAD. This software provides the buttons and sliders and other controls that send messages to the Arduino CPU. The final type of software is loudspeaker design software running in a PC or other “heavy” client that lets the user read ...
I am working on a project in which I need to have an ESP32 connected via serial to another ESP32 and at the same time to a Nextion HMI. I also need to communicate from the central ESP32 to these 2 devices concurrently ( having the serial communications in the "central" ESP32 open ...
