8051 Microcontroller

Sending MSG through GSM module

this project present a way to transmit textual data by use of GSM module and a brief introduction about AT commands. As a GSM module works on AT commands for communication our controller is programmed to send all these commands according to our reliability. you can also check these commands through hyper-terminal on your pc before designing your code and we also recommend you to check these AT commands on your pc.

RFID interfacing with 8051

this article covers rfid interfacing with at89c51 working at 12Mhz frequency.an rfid module is used for communication, is consisted of a reader and transponder . a transponder or tag communicate with reader through radio waves by receiving and transmitting signal. each tag has unique serial number  which is identified by reader.

Reverse parking alarm

As we all aware that sound is a function of frequency using this concept we can generate tune of different frequency. this property can be used as application purpose for producing specific sound while reversing your car.this is advanced model of RC-CAR we have designed earlier.it is assumed you know how to interfare LCD and DC-motor with MCU

Relay connection with 8051

this tutorial will give you small illustration of relay working with 8051.there are many situation where embedded system has to control large voltage or large current. in such case circuitry of embedded system which is operated at low voltage or low current can not drive. a relay is a elctro-mechanical device  which is used to isolate two circuits electrically and connect them magnetically.it is assumed you know to interface LCD

RC car(wired) using 8051

in this tutorial we'll be working on rc car that is connected directly from your car to be operated to remote through wire. remote having four switches used to customize four different modes of operation i.e moving forward,reverse,turning right,turning left.
