PROCEDURE 

 

The Procedure describes how to assemble various SMD (Surface mount devices) on PCB board which has fabricated,in experiment no. 3 i.e PCB Design and Fabrication and how to Program a Microcontroller  

         

Step 1.  Board is fabricated & Ready with component assembled on it ( EXPERIMENT NO. 3 ) refere fig 4, Now                     uploading the program on microcontroller ( Step 6 onword)

Step 4. Fig  5- it is 2 pin MTA connector- Connect at the Left side of the Ready PCB 

Step 5. Fig 6 - it is 5 pin Programming ISP connector -Connect at the Right side of the Ready PCB

 

                     

                                                       Fig 5                                                             Fig 6

 

Step 6. Connect this circuit to the parellel port of the PC. & run following command on Terminal
