Question: Can I use the TWS-434 & RWS-434 RF modules for serial communications..?

Answer: You bet. Click HERE for a complete project using these modules to control a hobby robot using a PC joystick with PicBasic & asynchronous serial control techniques.

Question: Where can I buy the TWS-434 & RWS-434 RF modules..?Figure 1. RF 4 channels remote transmitter circuit

This is a very simple RF transmitter circuit that consists of the Holtek HT-12E encoder chip and AM 418MHZ-transmitter module (WZ-X01). Using the hybrid RF xmit/receive modules make building the RF remote control a lot easy.

The transmitter can be powered with any voltage from +3 to +12V. The total current consumption is less than 5ma. Depending on the supply voltage, you may need to select a difference resistance value for the oscillator resistor R1. The recommended oscillator is Foscd (decoder) = 50 Fosce (encoder). See data sheet for more details.Where can I get a schematic diagram for a simple RF remote control circuit?
I need a simple remote control circuit just for turning on and off a LED. In fact, I have searched for appropriate ICs but since I am new in electronic circuit design, I only found some 5-functions transmitter and receiver ICs. So, can anyone give me some directions?

The individual security code of the transmitter is preset by dip-switches S5, up to 256 combinations.

When any of S1-S4 is pressed the /TE pin is pulled low, and power is applied to both the encoder chip and transmitter module, the encoder then starts scanning and transmitting the status of the 12bits address and data serially.


Answer: Right HERE........



The TWS-434 and RWS-434 are extremely small, and are excellent for applications requiring short-range RF remote controls. The transmitter module is only 1/3 the size of a standard postage stamp, and can
