Checking Battery Capacity with Arduino: Temperature Monitoring and Type Selection

Here is my Arduino battery tester, designed to explore the performance of various types of batteries, including 18650 and acid-based ones. Successfully tested even with a 6V lead-acid battery with a capacity of 4.2A, this device provides battery capacity readings in milliampere-hours. In fact, it’s an old article that I had never published before, but I have revisited and decided to publish it now.

BNO055 for esp32, esp8266, and Arduino: Gyroscope High Rate and Any Motion Interrupt 0

BNO055 for esp32, esp8266, and Arduino: Gyroscope High Rate and Any Motion Interrupt – 6

This latest article in the series explores how to use the BNO055 sensor with ESP32, ESP8266, and Arduino to achieve gyroscope high rate and any motion interrupt. The BNO055 sensor combines an accelerometer, magnetometer, and gyroscope in one module, making it ideal for accurate orientation tracking.

BNO055 for esp32, esp8266 and Arduino: enable INT pin and accelerometer High G Interrupt 0

BNO055 for esp32, esp8266 and Arduino: enable INT pin and accelerometer High G Interrupt – 5

Continue the series of article about the Bosch sensor BNO055. In this part of the tutorial, we will learn how to enable the INT pin of the BNO055 and configure the accelerometer High G Interrupt. The High G Interrupt is triggered when the accelerometer detects a sudden acceleration event that exceeds a specified threshold and duration. This can be useful for detecting impacts, falls, or other sudden movements in a variety of applications.

i2c Arduino SAMD MKR: additional interface SERCOM, network and address scanner

I love the I2C protocol, and when I need a sensor, every time I try to find one with this protocol, I have also written some libraries for various sensors that use I2C.
In this article, we will learn I2C basics, analyze the Arduino SAMD MKR management, add interfaces with SERCOM, and create a heterogeneous network.

BNO055 for esp32, esp8266, and Arduino: wiring and advanced Bosch library – 2

This is the second article on bno055. If you need basic management, you can refer to the previous article “BNO055 accelerometer, gyroscope, magnetometer, and orientation software”, but if you need advanced management (and more complex) with interrupt, you must read this article also.

BNO055 accelerometer, gyroscope, magnetometer with basic Adafruit library – 1

We are going to discover BNO055, a triaxial accelerometer, a triaxial gyroscope, and a triaxial geomagnetic sensor with a 32-bit cortex M0+ microcontroller in a single package.
In this first chapter, we start a basic usage.
