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 microcontrollers for Arduino to ESPs. This post will review how to use this sensor in projects. How to add the DHT 11 library in Arduino … Read more
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 facilitate communication between as many as 119 components. The I2C system is made up of 4 pins, they are power (Vcc), ground, SCL, and SDA … Read more
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. For example, I2C technology is used in robotics to control all the different parts and aspects of the robot. Most electronic devices today make use … Read more
