Complete ESP32 tutorials starting from basics to advances level. ESP32 is a famous development board for the internet of things applications. Although, other IoT development boards are also available in the market. But this board gains popularity among embedded developers and hobbyists in a short time. Because of its on-board many features such as Bluetooth, BLE, WiFi, Crypto-Engine and many others.
In this tutorial, we will learn to interface MPU9250 9-axis Gyro Accelerator Magnetometer Module with ESP32. Firstly, we will see the introduction of this 9-DOF MEMS sensor module, pinout, and specifications. In the end, we will see an example to measure 3-axis values of Gyro, Accelerator Magnetometer We have a similar guide with Arduino: MPU9250 … Read more
In this tutorial, we will perform UART or serial communication between two ESP32 boards using UART hardware library of Arduino IDE. To debug and program ESP32 using a USB port, the serial port which is known as Universal Asynchronous Receiver/Transmitter (UART) Communication is used. For most sensors and systems, the main communication method is considered … Read more
