This shield adds a pair of infrared transmitter and receiver to your Arduino. The spare area can also be used as breadboard. Interesting sample project is WiFi TV remote control using Android smartphone.
First, we need to configure the Juniper wifi shield. When use AT command to configure the Juniper WiFi shield, remove ATMEGA328P on the Arduino, short J4 (Pi1) and J5 (p2), Short J4 (pin2) and J5 (pin1), then connect the Arduino with Juniper installed to PC.
Using serial terminal console on PC, the configuration steps are as follows:
AT --- Detect if module is connected to the virtual COM, and if the module can receive the AT commands from the host
[OK] --- The response from the module.
AT+WD -- Disconnect from the current network
AT+NDHCP=0 --- Not use DHCP
AT+NSET=192.168.1.2,255.255.255.0,192.168.1.1 --- Set fixed IP, network mask, gateway
AT+WAUTO=0,LS,,01 ------ Set mode "STA", connect to SSID "LS" and use channel -1
AT+NAUTO=1,1,,2000- -- Set TCP(1) server, and port is 2000
ATC1 -- Automatically reconnect after reset
AT&W0 -- Automatically save
ATA -- Automatically connect to IP SubNet Gateway 192.168.1.2: 255.255.255.0: 192.168.1.1
Step 2: Remove Juniper, Download IRSend code to Arduino, and then reinstall Juniper to Arduino, set the Juniper to talk to ATMEGA328 through UART. The setting is as follows:
J4(pin1) is connected to J4(pin2), J5(pin1) is connected to J5 (pin2).
