Wifi communication with microcontroller

AI Thread Summary
The discussion revolves around selecting the right devices for establishing WiFi communication between a PC and a microcontroller (MCU) for displaying messages on an LCD. The user is considering options like the Black Widow, an Arduino-compatible board with a built-in wireless module, and the MRF24WB0MA wireless module for PIC microcontrollers. Concerns are raised about the complexity of wireless links and the importance of choosing products with strong support and documentation. The necessity of understanding specific project requirements such as range, power, size, price, and latency is emphasized. Ultimately, simplicity is recommended, with a caution against the potential complications of wireless communication.

Hi, I'm doing a project to send messages from a PC to a micro controller using WiFi. The MCU will intern display the message on an LCD. I have doubts about what devices I should buy to make the wifi communication and also what type of MCU I need to buy?...Any suggestions...
 
Engineering news on Phys.org
What are the devices found so far and why do you doubt them?
 
I have done some research but haven't found any devices so far and I needed suggestions on which MCU comes with wireless module or do I need to buy the wireless module separately??...I only need to send a maximum of 32 characters message since the LCD is 2 by 16.
 
actually I found out I can use Black Widow which is an "Arduino Duemilanove compatible clone but it has some components switched out for surface mount equivalents to free up space for the wireless module" http://www.seeedstudio.com/depot/blackwidow-10-p-613.html?cPath=79_82...I am not sure which components have been switched..

Also found out on MRF24WB0MA wireless module which is connected to PIC microcontrollers via a 4-wire SPI interface...so which option should be sufficient and less complicated to implement my project??...thanks
 
I think it will be difficult for anyone here to judge which will be sufficient as we don't know the requirements of the project. For example, is there a range, power, size, price, or latency requirement (to name a few)?

I guess my first suggestion would be to avoid wireless links. Especially if you want to keep the project simple.

And if it absolutely must be wireless, go with whatever product comes with the best support and documentation because you're definitely going to need it. Wireless links, and their drivers, have a way of breaking in ways you wouldn't expect.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
