My Project is remote control of Pumps. I want to know whether my setup works or not. I have a mikroe
SpeakUP which works at 3.3V. It has UART pins and it gives out Voice Msg Index (int value) like 0,
1, 2, 3,... through its Tx pin. I want to interface Xbee's Rx pin to Tx pin of SpeakUp and 3.3V pins
of XBee and SpeakUp to +ve of CR2032 battery and GND pins of XBee and speakUp to -ve of CR2032
battery. The receiver will have a Arduino Mini Pro 3.3V version and a XBee Pro. XBee's Tx pin will
be connected to Rx pin of Arduino working at 3.3V. GND pins of XBee and Arduino will be connected to
GND and 12V power will be given to Vin pin of Arduino and from Vcc (3.3V) pin of Arduino power is
given to XBee. RESET pin of XBee will be left unconnected. The receiver XBee has to get 0,1,2,3,...
and based on the value received operate different pumps through BC337 and 12V relay's. Can the Reset
pin of XBee left unconnected ? Will my setup work ? In Transmitter can I leave Tx pin of XBee
unconnected ? In receiver can I leave Rx pin of XBee unconnected ?
