Fourth day, Tuesday (10/07/2012)

Alhamdulillah, Thanks to Allah we meet again and I still go on my journey at UTeM Holding. For 4^th day during my practical at UTeM Holding, as usual I came at 9 a.m. and start preparing my blog to be update. After finish my updated, I continue my unfinished through hole soldering with ask to Mr. Mazran to supply the insufficient component. After I get the component I continue to finish my work. After finish and make an inspection at that work, then the next flow is to test the circuit were it is functioned or not. The tester equipment is vibrate sensor and LCD display.

VIBRATE SENSOR

This sensor been functioned as an input at AN0. When the sensor interfacing the vibrated, it will send the input to the PIC 28P by AN0 and connected to PIC leg number 2. The PIC are been programmed by PIC C Complier V4.038 where it been program to execute the LED to blink when it receive the input from vibrate sensor. PIC leg number 15 will connected to LED for the output. During my test time, I just shake the vibrate sensor to get the result (LED blink).

LCD DISPLAY

This LCD are been functioned to display what been programmed at PIC 28P. As usual the PIC must be set by PIC C Complier V4.038 to display what it required. During my test, my friend Azlan has set to write a “good” and when the supply been attach to the PCB, the LCD will display “good” means that my PCB been pasted. Since I not very similar to do a command at PIC with using PIC C Complier, that’s why I ask Azlan to help.

Figure show that the way to test the PCB with first circle show that the supply and second circle show the result for vibrate sensor. The LCD display will display the result.

After I’m finishing my work, Mr. Mazran give a task to understanding the AT command. He guide us to find the AT command with find it at cytron.com.my and then find the GSM modem, and then go to the manual. The page are about the introducing the GSM Modem, and the tutorial about control and monitor via SMS.
