![]() The display screen refreshes the data value once every second. If the data can be transmitted once every second, the baud rates are around 96bits/sec or 96 baud. Suppose the data is of 12 bytes, then each byte is converted into 8bits so that the total size of the data transmission is about 96bits/sec of the data (12bytes*8 bits per byte). The number of data bits that can be transmitted per second is called as baud rate. ![]() ![]() The data transmission rate is referred to as the baud rate. This serial data is transmitted with respect to certain clock pulse. As the microcontrollers work with the digital data, the information from the analog sensors, actuators and other peripherals is converted into one byte (8-bit) binary word prior to being transmitted to the microcontroller. In the embedded system, control sensors and actuators data is received or transmitted to the controller devices such as microcontrollers so that the data is further analyzed and processed. Electrically-coded information is called a serial data, which is transmitted bit by bit from one device to another through a set of protocols.
