UART in AT89s52 / Serial communication using AT89s52

UART (Universal Asynchronous Receiver Transmitter), a hardware component which are available in almost every microcontroller is used to transmit a byte of data serially through a single wire. It converts a parallel sequence of data into serial data i,e bitwise data to communicate between devices through single wire.

Raspberry PI

Raspberry Pi developed by The Pi foundation of UK is a low cost credit card sized computer which is able of using standard mouse and keyboard and can be plugged with the computer monitor.

Intel Quark SoC X1000 Series

The Intel Quark SoC X1000 is Intel’s lowest-power secure SoC which is single core, single-threaded processor in a 15mm x 15mm package. Some features of this chip are:-

Temperature based device Control system

A temperature based device control system which uses AT89s52 and LM35 temperature sensor is an embedded system which controls external devices(mainly an household appliances heater,fan,coolers and many more) by monitoring the temperature obtained from temperature sensor.

Line Tracking Robot using AT89s52

Previously, we discussed on line tracking robot without using microcontroller. Today, we will be building a simple line tracking robot which uses AT89s52 microcontroller that acts as control unit to provide decision to the robot. This following robot will also be able to detect cross or junction in the track.
