Designing the circuit for the DC motor and bluetooth system. The bluetooth remote control is used to open and close the curtain. Below is the block diagram for your reference. 2. You can make use of your mobile phone, write a J2ME application for communicating with your hardware. that will also give you extra control and a nice

GUI interface. GUI is just a graphical user interface. its not related to windows, but its a term used for interface that is graphical to user. can be on any platform or even without platform. 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. 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 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 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. ajay want to say that u first complete...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
