To connect multiple I2C, we have to address each slave device on the I2C bus. I assume you are using the Arduino as master and the other devices as slave. In that case each slave device will have an unique I2C address using which we can communicate with the respecti...
The TCA9548A I2C Multiplexer Module is to enable to connect devices with the same I2C address (up to 8 same address I2C) hooked up to one microcontroller. The multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pin with your command. The multiplexer itself i...
The I2C communication bus is very popular and broadly used by many electronic devices because it can be easily implemented in many electronic designs which require communication between a master and multiple slave devices or even multiple master devices. The easy implementations comes with the fact ...
I2C protocol uses addressing therefore multiple slaves can be controlled from a single master. When we use 7-bit address, 128 unique addresses are available for the communication. To connect multiple slaves to a single master, follow the below diagram, connect pull-up resistors with the SDA and...
The physical hardware of Arduino is the board itself. However, when it comes to Arduino boards, there are multiple varieties with different functionalities. Today we will be looking at ourSeeeduino V4.2, which has the same functions as one of the most popular Arduino boards – the Arduino UNO...
I notice that the configBlock gets written to the chip every time you want to take a measurement (in the function startMeasurement). The configBlock's first byte is the device address. Is there a nice way to change the device's address t...
Introduction to Visual Designer Proteus Visual Designer for Arduino simulation quickly and easily allows you to design and test Arduino projects without the need for programming experience. Watch Video Tutorial: Getting Started This video shows how to create a simple PCB in Proteus EDA Software fro...
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC wh...
Connecting or daisy chaining two or more I2C devices. Multiple branch cables can be used to extend I2C busses. Connecting two devices that need to work at the same time. For example, a LED and a Relay could be connected to a Grove Shield using a single Grove Branch Cable. It would the...
