Circuit Diagram

The following diagram shows how to connect the OLED display to the ESP8266:

Steps for the Experiment

1. Connect the OLED display to the ESP8266 via the I2C interface.
2. Write a program to display data on the OLED display, such as Wi-Fi status or sensor readings.
3. Upload the program to the ESP8266 and connect it to your Wi-Fi network.
4. Observe the displayed information on the OLED screen.

Explanation

The ESP8266 can communicate with the OLED display using the I2C protocol, allowing the display of various information on the screen.

Results and Observations

• The OLED display should show information as programmed, such as the current Wi-Fi status or sensor readings.
