Connection Diagram– OLED with ESP32 and Potentiometer Required Components: ESP32 board Potentiometer 0.96-inch SSD 1306 OLED Display Breadboard Connecting Wires As you can see above, we have connected all the VCC terminal of OLED with a Vin pin of ESP32. The SCL terminal of the OLED is conn...
You can checkthisprevious post for an explanation on how to install the libraries needed to interact with the OLED from the ESP32 and how to get started. It also includes the electric connection diagram between the ESP32 and the SSD1306. Additionally, we will need a library that will take ...

Here we have modified the below example as per the above interfacing diagram connection. HC-SR04 Ultrasonic Sensor Code for ESP32 /* Ping))) Sensor This sketch reads a PING))) ultrasonic rangefinder and returns the distance to the closest object in range. To do this, it sends a pulse to...
5. Circuit Diagram The circuit diagram of ESP32 with DS1307 is simple, with just four wires that need to be connected. You can shorten the I2C wires SDA and SCL of both the OLED and DS1307 sensors. Similarly, to power up both these sensors, the 3V3 and GND pin of the ESP32 board...

The SCL terminal of the OLED is connected with GPIO22 and the SDA terminal of the OLED is connected with the GPIO21 pin of ESP8266 NodeMCU. The grounds of all three devices are common. Assemble the circuit as shown in the schematic diagram below: ...
If it works, then you can solder the10 uF electrolytic capacitorto the board. Since theENand GND pins are far apart from each other, you can simply connect the capacitor between theENand theGNDof the ESP32 chip as shown in the schematic diagram below: ...
