Required components and tools are included as per this workshop. • Do no tampering with the components and tools without instructions. • Keep safeyour components, missing and destroyed component not be responded by us. • Do not ground yourself while soldering, and other time you should grounded. • Every time use solders flux while soldering and do not use more solder wire while soldering. • Please listen every point carefully & work as per instruction, don’t go forward. • Do not waste battery. • Please keep silence & maintain discipline.

Introduction to L.P.T. port or parallel port:-

For Improvement & Research In Science & Technology Parallel Port is same as the printer port in the back side of computer. Parallel Port Interfacing is the simplest method of interfacing. Now parallel port interfacing is used for programming microcontrollers and hobby circuit.

Parallel port Parallel Port interfacing is the simplest method of interfacing. So it is widely used. The main problem with parallel port interfacing is that it has data transfer speed up to 1Mbytes/sec. USB interfacing are Available having speed near to 12MBytes/sec.

Pin diagram of L.P.T. port Parallel port is basically the 25 pin Female connector (DB-25) in the back side of the computer (Printer Port). It has 17 input Lines for input port and 12 pins for output port. Out of the 25 pins most pins are Ground and there is data register (8 bit), control register (4 bit) and status. HERE WE USE ONLY 8 PIN AND GROUND PIN:-

L.P.T. port contain 8 data pin these can be used to autonomous any system as your requirement. HERE 8 PIN are used for LED D.J. lightning. & any four pin is used for transmission of data.

TO TRANSMIT TER CIRCUIT

1. Made the connections for the LED. Lightning. 2. First four pin connect to the (GROUNG ENABLE) switch of the remote control VIA DIODE. 3. Install “user port” and do the program in “c” language.
