Bluetooth curtain system

You mean i can create a J2ME application using the tool in the link page?Is it to use the same coding in the website to develop a software to communicate between mobile phone and the controller?

yes i think so

see this project done by one of the site member

Can you help me in designing circuit the where the DC motor connected to a PIC microcontroller.

.How to program the J2ME application to enable the dc motor to move reverse and forward as it is also connected to a PIC microcontroller?Do i need additional circuit?

hi nagufever
dc motor cannot be controlled directly to pin of the microcontroller u have to need of h-bridge circuit to do this
for h-bridge see this link

http://www.kmitl.ac.th/~kswichit%20/LFrobot/LFrobot.htm

dc motor speed can also be done by using h-bridge with pwm but if u want to use simple on off it then also h-bridge can be used or use simple relay control method

program the J2ME application in such a way u send any character in J2ME coding blue tooth receiver receive that character and sent to pic then pic should know that what have to done it this character received

and i think motor connection should be as in picture
i edit and upload

here is the motor connection block diagrm

hi majoka,
which pin do i connect the bluetooth receiver if i use PIC16F877? how do i read the datasheet to know which pin to connect which component?how to know which pin to connect the input from LM35 sensor and the output for motor?having trouble to understand the datasheet.

LM35 will go to analog input pin you can select any. motor will be connected through a motor driver e.g. L293D (see dc motor tutorial for info on connections). finish motor rotation part first then go to bluetooth.

bluetooth transceiver probably connected on serial port. its better you select a Bluetooth module to move ahead.

hi ajay bhargav,
what do you mean by 'finish motor rotation part first then go to bluetooth'?what is the difference between bluetooth module and bluetooth transceiver?

what do you mean by 'finish motor rotation part then go to bluetooth

ajay want to say that u first complete motor driving portion mean if ur using h-bridge or whatever method try to run first so its sure that this portion is working properly
it is useful in step by step troubleshooting
after completion of this portion goto bluetooth side mean going 2wards project in step by step

what is the difference between bluetooth module and bluetooth transceiver

bluetooth module normally a bluetooth reciever or it may be a tranmitter
bluetooth transceiver is a transmitter and reciver in a one package
