The two SCD41 sensors we want to connect have an I2C address of 0x62, which cannot be changed. Therefore, to communicate with both sensors from the micro controller, we will use a separate I2C bus for ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

Displaying data on an LCD is one of the most common tasks in Arduino projects. Traditionally, we connected LCDs using many wires, but with I2C LCD modules, the same task becomes simpler, cleaner, and ...

The library can be compiled for plain Linux (for example, raspberry spi), or you can use it with plain avr-gcc compiler without Arduino IDE. It supports monochrome and RGB oleds and has debug mode, ...

As embedded systems continue to power everything from IoT devices to automotive applications, understanding communication protocols like I2C and SMBus is essential for engineers and developers. These ...

Spread the love“`html Connecting sensors to Arduino opens up a vast array of possibilities for hobbyists and professionals alike, transforming ideas into functional prototypes and projects. Whether ...

Sometimes there’s just no substitute for the right diagnostic tool. [Ankit] was trying to port some I2C code from an Arduino platform to an ARM chip. When the latter code wasn’t working, he got clever ...
