I want to do I2C communication between esp8266 and arduino nano but it not work the connections i made GND to GND D1 or (GPIO 5) (esp8266) to A5 (Arduino nano) D2 or (GPIO 4) (esp8266) to A4 (Arduino nano) I connect both of them separately with my computer it shows me nothing in the serial mo…

Hi Sir: I am seeing your this post also when I used it I got the same results as your's [image] Sending data from Arduino to ESP8266 via I2C communication Networking, Protocols, and Devices I am giving below test sketches; where, the ESP8266-I2C Master receives the follow…

The Wire.begin() does not look correct. Nowhere do you tell the ESP8266 what its I2C address is, and normally you would not specify an address for the master device.

Dear check these codes here i mention the slave address in both devices Arduino nano code: ''' #include <Wire.h> void setup() { Wire.begin(8); Wire.onReceive(reader); Wire.onRequest(request); Serial.begin(9600); } void loop() { delay(10); } void reader(int how) { for(int i=0;i<how;i+…

[image] ahmed431644: I want to do I2C communication between esp8266 and arduino nano but it not work 1. Practically, ESP8266 is 5V tolerant; so, it can be directly connected with 5V-devive Arduino NANO. 2. Connect ESP8266 (I2C Master) and Arduino NANO (I2C Slave). ESP8266 does not work as…

[image] ahmed431644: Because my task is to perform I2C communication between them or use arduino nano and esp32-cam but with esp32-cam i am confused with it's connections so i choose esp8266 and arduino nano Do you have the following gadgets to exchange data between ESP32-CAM Module and Ardui…
