sketch : sniffer_433_TX (sister of "sniffer_433_RX")
Author : Peter Matthews (CurlyWurly) May 2017
Desc : Copy the "int codez[]=.." line manufactured by the sister sketch "sniffer_433_RX"
and paste it into this sketch so that this sketch can spoof the original transmitter.
INFORMATION
N.B. Connect pin 3 (txpin) to the TX module input
N.B. Copy the output "int codez[] = ...." from the "Sniffer_433_RX" sketch and paste where marked below
N.B. The sniffer sketch just outputs a set value of 35 in code[0]. This means that you may have to
experiment using a different "repeat" value (usually a value of 15 - 45 is OK)

sketch : sniffer_433_RX (sister of "sniffer_433_TX")
Author : Peter Matthews (CurlyWurly) May 2017
Desc : When a static 433 transmission is received, a "int codez[]=.." line is output to the serial bus.
Copy this line and paste it into the the sister sketch "sniffer_433_TX"
INFORMATION
N.B. Connect pin 2 (rxpin) to the RX module output
N.B. Copy the output "int codez[] = ...." from serial bus and copy into the sister sketch "Sniffer_433_TX"
N.B. This sniffer sketch just outputs a set value of 35 in code[0]. This means that you may have to
experiment using a different "repeat" value (usually a value of 15 - 45) when used in the "TX" sketch
