begin by showing a video communication by RF (Radio Frequency) to be used to control our picture named "Speedy."
order to create this wireless remote control, use the following:
for the transmitter (TX)
to the Receiver (RX)
HT12E The CI and HT12D are Encoder and Decoder (encoder and decoder), respectively.
The HT12E is responsible for encoding the 4 input bits to make it possible to TRANSMISSION, while being TRANSMISSION said received at the receiver, are decoded by the HT12D.
The HT12E is responsible for encoding the 4 input bits to make it possible to TRANSMISSION, while being TRANSMISSION said received at the receiver, are decoded by the HT12D.
modules TWS315 RWS315 and are responsible for and receive the signal tranmisitr encoded via RF, these are assigned a pin (or paw) where you should put a copper wire is used as an antenna.
As we can see, the combination of these circuits, give us a perfect solution for RF communication. The main characteristics of this communication are:
- 315 MHz Frequency Modulation ASK
- maximum transmission up to 4 bits.
diagrams for connecting the ciruit are as follows.
I got these circuits by return mail RoboDacta ( http://www.robodacta.com.mx/ ) an online store based in Mexico City, where you can get these and other interesting circuits used for the mini-robotics.
You can contact them via email to inquire about products and doubts there.
- can also find a good overview of these circuits on page Robots Argentina ( http://robots-argentina.com.ar/ ) -
- Communication - Radio Frequency (description and operation)
- Communication - Radio Frequency (Test of an RF link)
hope this information will serve to implement the Wireless communication simple but very useful for their projects.
