How to Scan I2C Address in ESP32 Using Arduino IDE

↺ How to Scan I2C Address in ESP32 Using Arduino IDE

> ESP32 is a microcontroller-based platform that can interface with several devices to control different outputs according to the input. All communication protocols like UART, SPI and I2C play a significant role in ESP32 communication. We will be discussing Inter Integrated Circuit or I2C communication protocol in this guide and how to scan an address of a device.

How to Transfer Data Through Bluetooth on Raspberry Pi

↺ How to Transfer Data Through Bluetooth on Raspberry Pi

> Transferring data to Raspberry Pi may look difficult for someone who doesn’t want to bother transferring it using the options like USB, email, or FTP server. Though these options are mostly utilized for data sharing from any device to Raspberry Pi, but if someone is interested in using the Bluetooth service for data transfer, he/she can follow this article for a detailed guideline. In this guide, we are going to discuss how to easily transfer data through Bluetooth on Raspberry Pi.
