In this case, the protocol name is SAMSUNG, the length of the command code
is 32 bits, and the command code is E0E040BF (the hexadecimal number we
grabbed in Grabbing Remote Control Codes, on page
We already used the Arduino as a web client in
Arduino, on page 163, but now we need to turn it into a web server. The server
waits for new HTTP requests like the one shown previously, parses the URL,
and emits the corresponding infrared signal.
We ll hide all of these details in a class named
as easy and as concise as possible, we ll make use of both the Ethernet and
the IRremote library. The
sophisticated examples of Arduino code. Here s its interface:
RemoteControl/InfraredProxy/infrared_proxy.h
#include <SPI.h>
#include <Ethernet.h>
#include <IRremote.h>
class InfraredProxy {
private:
IRsend _infrared_sender;
void read_line(EthernetClient& client, char* buffer,
bool send_ir_data(const
bool handle_command(char* line);
public:
void receive_from_server(EthernetServer server);
};
After including all libraries needed, we declare the
a member variable named
to emit infrared control codes. Then we declare three private helper methods
and the receive_from_server
InfraredProxy class.
Let s have a look at the implementation of all methods. We ll start with
