Introduction to ESP32 Bluetooth Serial Communication Using Arduino IDE Serial communication is important when it comes to microcontrollers as it allows devices to exchange data between them. ESP32 comes with UART and multiple other communication protocols that allows it to exchange data with a PC and...
Learn how the UART serial communication protocol works with the ESP32 using Arduino IDE: the basics of UART, default and custom UART pins, basic functions, communication between boards.
Learn about SPI communication protocol with the ESP32 using Arduino IDE. We’ll take a look at the ESP32 SPI pins, how to connect SPI devices, define custom SPI pins, how to use multiple SPI devices, and much more.
As per the above interfacing diagram, you can simply connect the ESP32 cam board with Arduino. Confirm that you have connected GPIO0 through GND & click on the upload button. When this code uploading is completed then take away the jumper wire from GPIO0. Once connecting & code uploading a...
