The term universal means that transmission speed and data format are configurable. As it is asynchronous it doesn’t need to send clock signal along with the data signals. UART uses two data lines for […]

A PIR (Passive infrared) sensor can be used to detect these passive radiations. When an object (human or animal) emitting infrared radiations passes through the field of view of the sensor, it detects the change in […]

We use ultrasonic waves because they are relatively accurate across short distances and don’t cause disturbances as they are inaudible to human ear. HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to […]
