I already connect the node red to the ESP32 to send the signal to the arduino and to the light bulb. My problem is that I send the brightness which is from 255 until 0, and the serial monitor from the arduino received random values from the node red. Like -2000, 1000 and not like what i send which is 255-0. I you guys have a solution on how to make dim light?
@daniel2g Daniel Welcome to the forum! We will be happy to help but there is a lot of information you haven't given use that makes it difficult to help you. Basic information like
- what version of NR and node JS are you running (you can get this from the startup log)?
- how are you communicating between NR and the esp32?
- what software do you have installed on the esp32 (ESPEasy, Tasmota etc) or is it your own code
- what kind of 'light bulb' are you using?
- how do you know that values the arduino is receiving
- what node (full name please) are you using to sendthe data to the esp32?
- have you put a
debugnode on the output of the node feeding the node that sends the data to see what the data sent is? If not please do that. - can you create a small flow to replicate the error - if so please provide it.
