! Name !! Pin1 !! Pin2 !! Pin3 !! Pin4 !! Pin5
| 433/315 Transmitter || Antenna (extra one close to other end)|| VCC || Data output || Data output || GND
| 433/315 Receiver || Data Input || VCC || GND
== Simple Demo Test ==
# Connect VCC GND to your arduino, for TX, connect to MCU 1 pin 12, and for RX, connect to MCU 2 pin 11. 3 wire connects for each, and 6 in total.
# For TX and MCU1, upload sketch named transmitter sketch from virtualwire library, and for RX and MCU2, receiver sketch from virtualwire library.
#After finish uploading all the sketch, push reset button or TX MCU1 arduino, you should LED 13 flashing on TX MCU1 arduino, and another TX LED flashing or RX MCU2 arduino, this may be different due to the arduino board version, but at least two LED on each board should flicking!
# Open RX MCU2 monitor on computer, you should receive:
Got: 68 65 6C 6C 6F<br />
Got: 68 65 6C 6C 6F ("hello" sent from TX)<br />
