In this example we will explain how to make your own IR system for remote control and you will see how that system can be applied for directing mobile robot (or similar processes).
System consists of transmitter and receiver. IR LEDs emit light on frequency that is detectable with commercial IR receiver. How system works? On picture you can see how is NE555 times used to modulate IR light at 36 kHz.
In this article we will present you terminal for TCP/UDP connection. Often when working with internet or LAN based communication you will need simple terminal tool to check connectivity or test your hardware. There are many such software on market but usually you only need to send and receive data without advanced protocol analyzer complicated options. In these situations this is perfect program for you to finish the job.
Almost every new hardware has some kind of connectivity available. Wireless connectivity has many advantages such as easy connection, no wires attached, no additional connectors and there for robustness (you would be surprised that for example micro USB connectors are declared to have only few thousand cable release cycles before subject to wear out).
