The built in LED's on both Arduinos should blink simultaneously every two seconds. Upload the receiver code to the receiving Arduino, and watch the magic happen. Upload the transmitter code to the transmitting Arduino, then plug into into a power source.
If (vw_get_message(buf, &buflen)) // Non-blocking Vw_rx_start() // Start the receiver PLL running Add item to my note name note: Append your notes without using the app manually. Vw_set_ptt_inverted(true) // Required for DR3100 Ask Siri to help you manage the little details of life with these commands: Remind me to task at time: Easily set reminders for a certain date and time without filling out all the fields manually in the Reminders app. Upload the following code to the Arduino connected to the receiver: Connect bottom pin on receiver to black command strip Connect second pin from bottom on receiver to digital pin 12 on Arduino Connect fourth pin from bottom on receiver to red command strip Connect fourth pin from top on receiver to red command strip Connect third pin from top on receiver to black command strip Connect second pin from top on receiver to black command strip (top refers to where the receiver antenna is) Connect 5V on Arduino to red command strip Connect GND on Arduino to black command strip Vw_wait_tx() // Wait until the whole message is gone Vw_send((uint8_t *)controller, strlen(controller)) The offer is incredibly varied. Vw_setup(2400) // speed of data transfer Kbps Each of us met with incredibly inexpensive Ebay modules that allow wireless communication between Arduinos. Upload the following code to the Arduino connected to the transmitter: Connect third pin from top on transmitter to 5V power supply on Arduino Connect second from top pin on transmitter to digital pin 12 on Arduino Connect the top pin on the transmitter to GND on Arduino ('top' pin is the one farthest away from the 'ant' pin) 2 Arduinos (most types will work, Uno and Mega definitely will) Most people, though, do not have experience communicating wirelessly between Arduinos using Radio Frequency technology.
Many people have sent communications between an Arduino and another computer using a serial connection, perhaps in a course like CSE 132.
