Making your own universal remote control systems today is very easy. Such procure the relevant chips, assemble them and here goes, your hi-tech remote control device is working for you. Here we explain a couple remote control chips especially designed for the purpose. The IC TWS-434 along with its encoder chip HOLTEK`s HT-12E form a high class tra

nsmitter circuit, whereas the chip RWS-434 through its complementing decoder IC HT-12D operates as the receiver module. Both of the above modules are able to exchange 4-bits of discrete data for control four external loads separately. With the easy availability of accurate remote control chips, making your own universal remote control modules is today just a matter of few hours. We discuss a couple of compact RF remote control transmitter and receiver modules here using the chips: HT-12E, HT-12D, TWS-434, RWS-434 Making a hi-end professional remote control system at home is a child`s play now. With the advent of micro remote control encoder and decoders chips, making a RF remote control is today a matter of a few hours or rather minutes. Applications of remote controls made from these chips are countless; you may use it for controlling practically any electrical gadget that you can think of, the best application being for car security systems. A couple of remote control chips, the TWS-434 and the RWS-434 both complement each other, the first one being the transmitter and the later one the receiver. The chip TWS-434 is basically a tiny 4-bit transmitter module, which is able to transmit 4 types of coded signals discretely, whereas the RWS-434 exactly compliments these signals by receiving them and generating 4 discrete decoded signals at its outputs. However both the above primarily functions just as wireless sender and...
