How to add USB to radio controlled sockets « befinitiv. Radio controlled sockets are a great way to save power in your home.
Devices consuming more power on standby than the sockets do can easily be switched off with a remote. For example my desk lamp from a swedish furniture store consumes 10x more power (in the off state) than a radio controlled socket. Even if the sockets consume more power in standby than the attached electronic device, they offer the luxury of turning stuff off and on without even moving. In short: They are really handy. However, if you’ve installed the sockets, one sentence will often reoccur: Where the f*** is my remote?
» Adding web connectivity (via USB) to remote controlled sockets – Part 1 (hardware) Jake Rowan Byrne. Kit Review – akafugu TWILCD Display Controller Backpacks. Introduction Working with LCD displays is always useful, for debugging hardware by showing various data or part of a final design.
Furthermore, using them can be rather wasteful of I/O pins, especially when trying to squeeze in other functionality. Plus there’s the external contrast adjustment, general wiring and the time taken to get it working. Blog » Blog Archive » Finger print sensor with Arduino. Blaise Jarrett's Portfolio. This project enables your microcontroller to communicate in real time to a web browser.
I started this project after seeing a similar implementation on hackaday from mbed.org. Their implementation uses their own device, the mbed Cortex-M0 beta. Microcontroller Projects: Nokia 1100 LCD Interfacing with Microcontroller. Displaying content on a normal alphanumeric display is very limited ,we have to be limited with the font size and we can't draw any graphics also. but convention Graphics lcd are really very expensive so here is the solution, you can use Nokia 1100 monochrome LCD to display your large font text and graphics . the reason behind using this LCD is ,it is really very cheap and can be powered with 3 volts supply. so it is really good for battery powered application.
Adding USB connectivity to old benchtop tools. Improving the Beginner’s PID – Introduction « Project Blog. In conjunction with the release of the new Arduino PID Library I’ve decided to release this series of posts.
The last library, while solid, didn’t really come with any code explanation. This time around the plan is to explain in great detail why the code is the way it is. I’m hoping this will be of use to two groups of people: People directly interested in what’s going on inside the Arduino PID library will get a detailed explanation. Why pay for Serial LCDs when you can make your own? RF Link Receiver - 4800bps (315MHz) 315Mhz RF link kit [WLS105B5B] - $4.90. RF Link Transmitter - 315MHz. 315Mhz RF link kits - with encoder and decoder [WLS106B5B] - $9.50. I want to connect 4 door to 4 receiver, when a door open, a light will go on at the other end.
Is it the circuit I should choose for that purpose? If I understand, I have to solder a pin of the pt2262 so that every transmitter doesnt intefere one another. Transmitter Pin Size and Spacing What are the pins for the transmitter since they aren't the standard size? Where can I get it? The pin pitch of the transmitter is 2.0mm, we do not sell its wire for now. Answered by Deray Wu | 2014-03-24 Was this useful? Gerald Backer | 2013-03-25 I am curious why the Transmitter can only handle 5 volts. Hi, they are both working on 5V, the sickscreen on the board "12V" is an error.. Luo G.ss | 2013-03-29 Hi,this is a externally-sourced produce,all parameters are given by supplier,maybe there are some differences in the circuit. 433Mhz RF link kit [WLS107B4B] - $4.90. Hello, I need to broadcast sensor values (16 bits), to several receivers at the same time, 10 times per second (it means 10 messages of 16 bits per seconde). is it possible to use that 433 Mhz RF link for that ?
Or does it take more than 100ms to send a message ? Thank you very much, Arnaud Hi, I purchased 3 units, but the range is very limited (i get less than 10m in direct sight of view). Partlist Wednesday: NPN transistors. Every Wednesday we highlight a component from the updated partlist.
This week: NPN transistors Transistors do lots of analog tricks, but we only use them to switch high powered stuff with a weak microcontroller pin. Usually an LED. See the IR Toy, #twatch, PICqueno, or USB POV Toy for the sad truth. We’ve standardized on the BC818 for most stuff. If you’re choosing a substitute part be sure to check the pinout. Verify your schematic and footprints too. RGB Accent Lighting with Remote Control. Our good friend Tod Kurt, of ThingM, shows how to control a strip of RGB LEDs using the BlinkM MaxM driver and a FreeM IR remote receiver.
I used some similar strip lighting and a MaxM for a friend’s Halloween costume, and really liked being able to program the blink pattern via Arduino. The addition of an IR remote opens up interesting possibilities.
