This one is interesting just like displaying a custom message on LED matrix banner. Just from an Android phone on our finger tips. Change at anytime anyhow, at just one touch.
You might be thinking to stream video from your robot to your phone or laptop, or design a surveillance system like CCTV via beagle bone. So this post is for you. Here we will see how to install MJPG streamer on your Beagle bone and see its output on your WiFi enabled phone or other devices.
I am using Beaglebone Black Rev.C and Logitech C170 usb webcam. You can see a huge list of Raspberry Pi compatible peripherals list here. They are also compatible with BeagleBone. http://elinux.org/RPi_VerifiedPeripherals
The Raspberry Pi Foundation’s low-cost computer was an instant phenomenon upon its release in 2012, and now, just shy of three years later, it’s back with a new one. The foundation is today announcing the Raspberry Pi 2, an equally cheap, equally tiny computer that’s meant for use in electronics projects, assisting experiments, and teaching kids how to code.
There are two key changes on this new model: its processor is now a lot more powerful and it includes twice as much RAM. What doesn’t change is just as important: it still sells for only $35.
“It’s a major leap forward in terms of computing power for users,” says Mike Powell, a technology development manager for Pi distributor Element14. Powell believes that the Pi 2 will open up a lot of new opportunities because of its added computing power. “A whole wave of new applications are now possible,” he says.
Most if techie people know sixth sense technology and Pranav Mistry, right? Here’s a TED video almost all people viewed and suddenly became crazy about it. But if you listened this video carefully, you might be knowing that :
(Note: if you want to see code links directly, skip this part and see it at end of this post)
While demonstrating the interface at TEDIndia Conference, Mistry told Rediff, “I don’t want this to comply with some corporate policy. I want people to make their own system. Why not?” See this video carefully.
Sometimes we need some data or variable values to be retained back even after the system is turned off. So as soon as we again start back the system we need to know the previous values of some elements to identify the state of the system at shut down. So that now we can resume directly from that state only, not the initial state. In many cases this is required.
The whole simulation video is available at youtube link below:
You can download hex file and proteus simulation at end of the post.
This device can be used to control your home’s all 230V appliances directly from your PC. We can do it via the serial port of our PC. We have used the 8051 microcontroller here. We are communicating via the RS-232 port.
The circuit is designed in the proteus ISIS software. I have first simulated the circuit in the proteus so that all correction and debugging process is done in the PC itself. So we don’t need Continue reading
