An Overview Of The Wireless Infrared Link
In comparison to other wireless transmitter and receiver systems, this wireless infrared link is extremely low cost and easy to build. Many limitations exist, like the need to have line of sight, transmitter to receiver, however even with these limitations there are many applications for this type of wireless system. The IR link created in this tutorial showed you how easy it can be and how standard digital communication can be passed across the link. This was just a simple example, but it should be enough to get anyone started for bigger and better things with wireless IR.
What To Do Now
The next steps you could take, lead to many different directions. With the knowledge in this tutorial you can move forward and try to amplify the received signal so the transmitter and receiver don't have to be so close together, that is how TV remote control IR works. You can further experiment with the upper limits of how fast you can transfer data and how far with what accuracy. Since the parts are so low cost, the real limitation is only your imagination and desire to solve your wireless problems.
Conclusion
This was probably one of the more fun tutorials that I have written. Wireless, at least from the analog perspective, is usually a gigantic headache but when you move to an infrared based wireless system you don't have to deal with as much RF theory. This means more digital design, less analog design which is very welcome. The tutorial was successful as the data section showed you and hopefully you will now go and build your own wireless infrared link!
If you have any further questions, I implore you...don't be shy, take a look at the forums or ask a question there. I check them out regularly and love getting comments & questions.
