Bluetooth Controlled Electronic Home Appliances. Bluetooth Controlled Electronic Home Appliances is a simple project, where we can control different electrical appliances and electronic devices using an Android device with the help of Bluetooth Technology. We have already seen how a DTMF controlled home appliances system works in the earlier post. Operating conventional wall switches is difficult for physically handicapped or elder people. This project provides the solution to this problem by integrating all the electrical appliances to a control unit that can be operated by an Android application on a device Android smart phone or Tablet. The proposed system controls the electrical loads based on the data transmitted by the Android device. An Android application should be installed in users mobile or tablet to control the electrical loads. Using this Android application user can send the commands to the Bluetooth module to control the electrical loads. Wireless technology used in this project is Bluetooth. It can also be called as Bluetooth Controlled Electronic Home Appliances or Android based Home Automation System or Remote Password Operated Electronic Home Appliances Control System.

Here, the LCD Display is interfaced to the PORT1 of the microcontroller in 8 bit mode i. LCD are connected to PORT1. The three control pins of the LCD i. RS, RW and EN are connected to P3. GND and P3. 7 pins respectively. Also, a 1. 0K POT is connected to the Contrast Adjust pin of the LCD to control the contrast of the display. The TX and RX Pins of the Bluetooth Module are connected to the RXD and TXD pins P3. P3. 1 of the microcontroller. VCC pin Pin 4. 0 is connected to the 5. V and GND pin Pin 2. The Microcontroller communicates with Bluetooth Module using serial communication UART protocol. Use a baud rate of 9. Bluetooth. If you want to change the Bluetooth name and password then you need to use Bluetooth AT commands. Below are the few Bluetooth AT commands AT  Responds OK. Used to test the Bluetooth moduleATRESET  Responds OK. Used to reset the moduleATNAME  Responds with the module name. ATNAME  lt name Responds OK. Name should be less than or equal to 2.

Embedded Bluetooth Serial Communication Module AT command set. Electrical loads like Lamp and DC motor are connected to the P0. P0. 3 Pins through the 4 Channel Relay Module. Here, relays are used to switch AC loads using small DC voltages. NPN transistors are used to drive the relays. If you are using a relay module, then transistor and other important components to drive the relay are already embedded on the module itself. NOTE The Circuit Diagram shows connections of only one load. But the connections to the other loads can also be made in a similar fashion.

Vue is a Great Example of an Unfavorable Approach to Hardware Supporting Software. Shown above is a screen capture from an earlier version of AgilentKeysight Bench. Vue software. Now I have no idea. Because something went wrong with the update and while waiting for it to download again I discovered that Keysight started charging for software that used to be free. Heres some backstory Advertisement. A few years ago, I bought an Agilent 3. A benchtop digital multimeter. Back then, it came with a free Windows utility that allowed for easy data logging on a PC via USB. And then Benchvue came out. It wasnt perfect, but it was quite handy. Coming from my experience with Agilents digital multimeter utility, I was very optimistic about Bench. Vue, and how it would make it easier for me to visualize, record, and share data, such as voltage, current, and other related multimeter measurements. I bought a second AgilentKeysight multimeter, upgraded to an AgilentKeysight programmable power supply, and splurged on an AgilentKeysight oscilloscope. Benchvue was imperfect. It had a habit of crashing and disconnecting my multimeters when I was taking crucial data, and discussions with Keysights tech team didnt really help. I havent seen the connection failures in a while, because Ive given up on using the software for certain types of measurements with certain test accessories. There were other weird crashes that the Bench. Vue team tracked down to a certain way of launching the program in Windows. Years later, I am mostly convinced the specific dropped connections and missed data issues might have been with the multimeter hardware in some way. Maybe something between the multimeters and my computer Its never been sorted out, and mentioned Ive been less reliant on the Bench. Vue software. Thats what happens when something fails and disappoints you. But Benchvue was free, and it was useful. I upgraded Benchvue at some point, and probably once or twice more since then. After one of the early updates, it installed a bunch of other software on my computer, including a very annoying license manager that scans any USB drive or device thats connected to my computer. Its always been intrusive. There were new software licenses and a Pro version. But there were less featured of the different device apps that were free. Free lite versions. Okay I was annoyed. Bench. Vue offered the same digital multimeter functionality as the previous DMM utility, but at a price instead of being free. But that free option was still all I needed. Now, I went to upgrade Bench. Vue again, because why not. I was upgrading some other software on my computer. It removed the previous version, and installed nothing. All I have now is a bunch of bloaty license managing stuff, and a Bench. Vue troubleshooting utility that tells me everything is okay. Huh So I go online to download the full version. What do I learn Bench. Vue 2. 01. 7 has no more free function limited apps, EVERYTHING requires pricy license fees. So it went from free, to free with paid function upgrades, to paid software. I spent a couple thousand dollars on Keysight equipment, and now they want money for software functions that used to be free. I read that users who bought Pro licenses now have to work with Keysight on getting the newest version to work, since its a completely incompatible licensing structure. A search online shows that the previous version is still available, but for how long I cant find any of the free utilities that predated Bench. Vue. This is a great example of what NOT to do. Milwaukee has said their One Key app will always be free. I believe the same is true with Dewalt and their Tool Connect app. Flukes Fluke Connect app is mainly free, at least all of the functionality most individual users might need. Keysights Bench. Vue software was great when free, but its too buggy for me to ever pay for. The fact that I would now have to pay for software that was free makes me extremely hesitant to buy Keysight test and measurement equipment again. I have a BK Precision and Rigol equipment, and they come with so so software. My BK Precision electronic load software has some particularly amateurish aspects, but it was free and continues to be free. In my experience, Bench. Vue has the stability and bugs of free software, but I couldnt complain much, because it was free and it was useful. What Im especially steamed about right now is that Bench. Vue played a hand in my purchasing decisions, decisions Im starting to regret quite a bit. Getting the new paid version of the 3 Bench. Vue apps Ive used would cost me close to 1,0. Getting perpetual licenses for a bundle of their most popular apps, apps I might use someday, is over 2,0. Im going to try to reinstall an older version. Because Im NOT going to pay 9. Keysight test measurement equipment. I love or rather I loved my Keysight equipment, but this possibly irreparably hurt my impressions about the company. Maybe one day Ill pay for Bench. Vue app licenses out of necessity, but only if they very drastically improve it. Argh. Update The older version of Bench. Vue seems to be working just fine, but this hasnt done much to assuage my strong disappointment and frustration at Keysight. A lot of sites have Keysight product listings that still mention Bench. Vue as a free software option. Sections Editorial, Test Measurement.
