Hey guys, I'm doing a project on wireless notice board, and my codes are in assembly language 1. The wireless module is zigbee, and it's from pc to PIC, 2. The display is dot-matrix and data will be taken from EEPROM to be displayed 3. Only one way communication using USART from Zigbee to PIC6f628A 4. PIC will receive (...)
anyone who has an idea about the sms based wireless notice board using a led display & who has a schematic diagram? many thanks in advance. :)
i'm not shure, but currently using frequency is 27Mhz and use usb port. in that frequency is happened some confusions like - with one keyboard write on two computers and interferences with other radio-based devices i readed, don't see it:) recently i read that cypress offers new wireless USB chip for keyboards, mice. it work at 2.4 (...)
can anyone give me circuits on pc based wireless message board...i am using rf technology. the message board i'm going to use is the LCD.. i am going to use on my project. i am confused on both the receiver and the transmitter side...thank you so much...
There are other wireless chips from analog semiconductor and cyprus they can provide more than 20m of range easily but you can use high range RF transceivers with amplifiers and a good antenna to increase the range and give more current to the wireless kit ( under the range specified ) to increase the range But if you want to go for GSM you c

well it all depends in how much do you know of microcontrollers, PCB design and electronics overall... i think there is no microcontroller with integrated bluetooth, so the common approach is to use a main microcontroller and a bluetooth module, (someone like
I am working on a circuit that will control the selections on a arcade pcb. Basically I have a 6-in-1 arcade pcb switcher (a board that holds 6 individual jamma boards), when you press a button on a wireless remote it switches to the selected board. The wireless interface to the pcb board is (...)

Maybe you need a power supply which takes 220V input and outputs 5V DC for Arduino board. Arduino can take 9V. You can use 220V in and 9V DC out adpater whose DC power jack plug's center pin is +ve and other pin is negative. The eBay product that you showed was a remote operated relay circuit. It has a wireless transmitter and a wireless (...)

Hi Folks Anyone suggests a specific Xilinx Dev. board for wireless Designs like ZigBee, Bluetooth, etc. In other words, is there any board to have support for (for example): 2.4GHz Front-End .. Antenna .. FPGA with good DSP support .. etc. ?
Hi folks, If your company is looking for some help in FPGA or board design and need sometime with short availability notice, then send me a message. I have over 20 years of experience in electronic design in Sweden, US, Ireland and France in various industries such as industrial control (ABB), wireless (Ericsson), Robotis (TRIAB), (...)
Hi, I want to build a FPGA based prototype for uncompressed video over wireless connection with one box being transmitter and other a receiver(to display). The transceiver speed for HD video (1060) is 3-4 Gbps. But it would need an expensive FPGA board. I am thinking of VGA and i guess it needs around 1 Gbps (correct me if i m wrong). What type of
I recently built a solar-based system to power a custom (low-power) wireless board. This solar system was quite simple: Solar panel --- NCP1400-based PSU --- wireless board The whole system works well under direct sunlight. However, out of direct sunlight and even with strong indirect sunlight the solar panel is not (...)

I found this PIC18F2520 Interface board with XBee wireless Option on PIC18F2520 Interface board with XBee Option . My project requires programming a Pic18f to understand a temperature sensor and a pulse rate sensor , of course converting the data from them from analoge to
Hi all, Could you please help identifying these boards? The main one has a Microchip MRF24J40 wireless module and a PIC18F26K20. Soldered to it is a small board labeled "MICRO I/O" with what I guess is a sensor (because it has 2 axes A and B printed on it (the back has a stick: WSN 011)). Note: the chip is a Honeywell, but I cannot make
Hello, I would like to make an application for sending information from a PC to a remote (more or less) place with a wireless module. My intention is to use the rs232+comercial modem+433 wireless module. I have seen something similar. I don´t know much about modems so I would like to know how should I connect the modem to the wireless (...)
Can anybody recomend a good fpga development board using an xilinx device? Reasonably priced and available in the UK. I know the theory, need to do it for real. These days in the job market, you need to be able to cut it on the fpga front!
5W across that distance is definitely near to insanity.... imagine the loss. The most i've achieved was for 1.4W across 3mm for a contactless battery charger. Even with that, the component used is already discontinued! Nevertheless, do hope to share my experience and hopefully there's somebody who can replicate such wireless tansfer into a stand
once again .. you can use any ip stack project with mcu ... you have to send either tcp or upd packet form your first mcu board to ip adress of your other mcu board. the wireless modems will do the rest for you .. they will bridge your ip networks ... regards cancel
