How to make an I2C slave send data in an I2C system
The master device mostly controls the I2C slave device. In this post, we will send data from the master to the slave. This is useful as some projects require the
How to use Newping.h Library for ultrasonic sensors
Newping.h is a Library developed by Tim Eckel. It makes interfacing and using ultrasonic sensors much easier. The library can be installed directly from the Arduino IDE, or the zip
How to use L298N dual H-bridge motor driver
The L298N dual H-bridge motor driver is among the most popular DC motor drivers. It features a simple interface and uses fewer pins to connect to the microcontroller. Its method
How to use Serial communication between 2 Arduino boards
Serial communication refers to data transmission between two or more devices over a communication channel. Arduino Uno and other smaller variants have two (2) serial communication pins namely RX and
How to use DHT11 sensor
DHT11 is a four(4) pin sensor for measuring temperature and humidity. This sensor is cheap, small, and reliable for temperature and humidity projects. The DHT 11 works well with all
Multiple devices on a slave in an I2C system
A typical I2C system consists of two separate components or microcontrollers between which we intend to enable data transmission. The I2C system is handy in electronics design as it can
I2C communication between microcontrollers
I2C communication refers to the transfer of data between two devices. It stands for Inter-Integrated Circuit. It is a protocol that aids the communication/data transfer between two microcontrollers or components.
Interfacing I2C LCD with ESp8266
ESP8266 has become a common component for building IOT-capable devices. The I2C display module is a popular I2C technology that makes interfacing devices easier. It stands for Inter-Integrated Circuit. ESP8266’s
