hi, i know its been 5 years ago. I want to do the same but instead of removing RGB led driver i want to keep it and try to decode/encode IR signal with a ESP8266. would you mind to give me some advice on that?
@TechnoAutomation 5 ай бұрын
You can flash esp with tasmota ir firmware and connect ir receive led output pin to esp 8266 input pin. Assign that pin as ir receiver in tasmota firmware. Once this procedure is completed you can read ir recieved data in the tasmota web console. Recieved data encoding done by tasmota firmware out of the box. You also can pass encoded data to mqtt broker for further connectivity. I know it's completed but if you start , it will become easy. First tym tasmota firmware. It's easy to install and understand & good community support on social media and strong documentation on its repository.

I want to a make a home automation for my home. So that I am decide to control all the bulbs and fans through the home assistant or phone. I am not connect all relays and senaor through the wifi network because my home is big. Wifi range is to small for my home automation. So that I am decide to implement modbus for connect all relays and sensor. I thing Modbus is more reliable and easy to implement because the wired connection. I want to connect 10 node. Each nodes contains or hold the few relays and some sensor such as temp and humidity CT sensors mmwave sensor motion sensor. And each nodes connect through each other. And last node is finally connected to think client or Ressbery pi which is operated home assistant os. Please solve my problem and give the feedback
@TechnoAutomation 6 ай бұрын
Modbus is a master slave communication protocol. Each node will not talk to each other directly. Only the server can talk to all devices. For home automation wifi network is the best suitable communication method. If your wife's network is limited in range then you can use wifi repeaters. Or you can use esp now which is a light weight wifi communication protocol which provides mesh networking and nodes to nodes can talk to each other.

if x_medium < x_center - x_band: x_position -= 1 elif x_medium > x_center + x_band: x_position += 1 This part of code smoothens servo motion. SG90 has a resolution of 1deg. Hence we get 180 small steps to move from 0 to 180. We can't get an intermediate position so little gitter will always be there.

What is a bootloader? Rhetoric question
@TechnoAutomation 2 жыл бұрын
Bootloader is small piece of code which allows you to re-flash microcontroller using serial interface. Example:- you can program Arduino Uno using its serial rx,tx pins without much effort. But if you have Arduino Uno without bootloader then you need to program it using ICSP. In Circuit Serial Programming. If you have Arduino Uno without bootloader and you download blink program using ICSP it will start blinking led. But you can not reprogram it using serial port as there is no bootloader in it. Case B :- if you download bootloader in your Arduino using ICSP first then you need not to use ICSP to flesh new code. You can use serial port to re-flash it. I think I answered your question.

@TechnoAutomation 2 жыл бұрын
Esp32 & 8266 is 3.3V board. If you have used 5V for Max485 then signals from 485 module is 5 V pulse. In that case you have to used voltage level shifter or Potential devider to protect ESP32 or 8266. I have tried 3.3v Max485 & 232 board which makes voltage level compatible for esp. I have also tried 5V operated Max485 with esp8266. In This case I have used potential devider for RX pin of esp8266. Tx pin of ESP can directly connected with Max485 converter. Voltage level shifter parform best if you have Different voltage operated device.
