Learn how to decode transmitters using the 4-bit Holtek HT12E encoder, Linx Technologies CMD-HHLR-433 with 8-bit Holtek HT640 encoder, make your own 4-bit encoder & decoder ICs, send/receive wireless serial data between two 8-pin PIC microcontrollers, create an 8-pin serial encoder IC to replace the Holtek 8-bit HT640, work with the Linx long-range LR series RF modules, and even work with the Microchip rfPIC development kits. The LC4 receiver doubles as a development platform for the Linx long range LR receivers, or as a stand alone remote control solution with many flexible options. Together with the code examples we provide for the PicBasic Pro compiler, this can be one very flexible remote control system. The LC4 is available as a bare circuit board, with a pre-soldered LR receiver module, as a full kit, and a full kit with PicBasic Pro code examples on CD-ROM for several wireless remote control applications. Options:
PicBasic Pro Code Examples On CD-ROM: 3 NEW bonus code examples added 10/17/2007
Mechanical or Solid State Relays: The full kit versions include 4 x 10 amp mechanical relays. However, the LC4 can be easily configured for digital outputs with status LEDs to indicate when an output is on or off. Figure #3 shows how to install jumpers for digital control outputs. With the relays and relay diodes not installed, LEDs can be mounted in the pads just outside the relay diode pads. The LED cathode is to the left. The anode is to the right. Series limiting resistors for each LED are installed on the left. The LEDs provide visual ON/OFF status indicators for each digital control output.
Switched power from the drive transistors on the LC4 board is now routed to the screw terminals with short jumper wires. This allows for control of external hardware like solid state relays, buzzers, and other hardware that can operate from the LC4 boards DC power supply. As shown in Figure #3, +/- DC polarity markings have been added to the LC4 board silkscreen for easy identification when the relays are not installed. The left screw terminal for each digital output is switched ground from the NPN low-side drivers on the board. The right screw terminal for each output is connected directly to positive voltage from the LC4 board power supply. |
