Okay thank you

Where do I connect the Di in my esp32 (DEVKIT V1) regarding to the example you Provided it. In that example it's connected to GPIO 0. pin = Pin(0, Pin.OUT) You should probably use a level shifter, but I've heard people say it works without. The GPIO 0 is the same as the ground pin in my esp32 I thi...

also is it possible to run the LED strip using just the esp32? Yes. See http://docs.micropython.org/en/latest/esp32/quickref.html#neopixel-driver Note that you will need to power the strip from 5V, not 3.3V. I also recommend using a level shifter to convert the ESP32 pin (3V) to the WS2812 input (5...

Hello everyone, i am trying to use a WS2812B LED strip to work with a code that i have for the esp32. the code is a MQTT subscription code that subscribe to a temperature topic that i run on another ESP32. in this code if the temperature get higher than a certain degree, it will print a danger messa...

I am sorry, I know I am asking too much questions, but how to make another eap32 subscribe to the Topic that i have.

Thank you for the response, I will order the NeoPixel led and try to work with it and see if it will work.

I am sorry for not being clear in my answer. It will be awesome if you can tell me which led strip will work fine with the project I am working on it. I did my research and all I can find is the neopixel LED strip but I think it will not work fine with the project I am working with. I was thinking o...

For the internet problem, I already have a solution for it. I have a script that will connect to the internet my it self.I don’t have a library for the led strip. Also I need help making the code if that possible. Thank you

hello everyone, i am working on a school project and i need help with it. i have MQTT client code that will run on the ESP32.It polls the DHT-22 and publishes the sensor data to a topic called temp humidity. then i have another script that ran on the raspberry pi 3 that will subscribe to the temp hu...

Thank you for the help , I have a question, For the mqtt script, is it just for the temperature sensor or do you have other sensors that are connected to it.
