The schematic for the transmitter remote control is shown in Figure 646 The circuit functions by using the PIC 16C71 to monitor the position of the control stick and then send serial commands to the transmitter module When the control stick moves along the X and Y axis, the resistance values of two 100K potentiometers are varied The control stick and the two attached potentiometers are shown in Figure 647 Each potentiometer is configured as a voltage divider so that a unique voltage represents each position along the X- and Y-axis The voltages from the potentiometers are converted to 8-bit values by the internal analog to digital converters on the PIC 16C71 and then interpreted by the microcontroller Depending on the values, certain movement commands are sent in a serial format from the transmitter to the robot The remote control also has a programmable push-button switch and a light-emitting diode (LED) that can be turned on when certain events occur, such as during the transmission of a movement command The transmit229

ter module is the TXLC-434 transmitter, available from Reynolds Electronics at: wwwrentroncom The modules are based around Linx Technologies (wwwlinxtechnologiescom) LC series transmitter modules, as discussed earlier The transmitter module pinout diagram is shown in Figure 648 The only external part needed for the module to function is a 430 resistor that is connected from the VADJ line to ground for 5-volt operation If the resistor is not included, then the device will operate at 3 volts Using the module to transmit information to the receiver will be discussed when programming is covered

Amphibionics
PIC 16C71
The Microchip PIC 16C71 is very similar to the PIC 16F84 that has been used throughout the book The pinouts are identical The difference is that the pins on PortA of the 16C71 can be configured to take advantage of four on-chip analog-to-digital converters Another difference is that the chip is erased by exposure to ultraviolet light A small window on the top of the device allows light to get at the chip After the chip has been programmed, the window should be covered with a sticker so that it does not get erased if it is exposed to sunlight or fluorescent lighting The 8-bit resolution of the 4-channel high-speed 8-bit A/D is ideally suited for applications requiring a low-cost analog interface Use of the A/D converters will be discussed when the software routines are covered Although the 16C71 device was used in the book, Microchip now manufactures an 18-pin, flash erasable device with analog-to-digital converters, identified as the PIC 16F818 Figure 649 shows the PIC 16C71 with its ultraviolet erase window The parts needed to build the transmitter are listed in Table 64
