#include
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
  Serialbegin(9600);
  irrecvenableIRIn(); // Start the receiver
}
void loop() {
  if (irrecvdecode(&results)) {
    Serialprintln(resultsvalue, HEX);
    irrecvresume(); // Receive the next value
  }
}
 
Step 1: Assemble Circuit:
 
ou will need one Arduino for this I used a UNO, but just about any Arduino should work First wire up the infrared receiver that came with your kit There are 3 wires, PWR, GND, and SIG, I used port 11 for SIG Note! some readers have reported that their sensor has different wiring, double check it yourself
 
Step 2: Download IR Library
In order to reverse engineer the remote and obtain the codes for each button we are going to need to download and install the following library
https://githubcom/shirriff/Arduino-IRremote 
Extract the file in your libraries directory eg  ( C:\electronics\arduino-105\libraries )
note: I had to rename the library because the name was too long, I just renamed it to IR
Step 3: Add Library to sketch
 
With the IR folder ( or whatever you named it) now in your libraries directory, we can import it into a new sketch
Start a new sketch and the Click  
        Sketch->Import Library->IR
Step 4: Paste Code and compile
Paste the following code into the new sketch Then verify it compiles
#include
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
 
void setup()
{
  Serialbegin(9600);
  irrecvenableIRIn(); // Start the receiver
}
 
void loop()
{
  if (irrecvdecode(&results))
    {
     Serialprintln(resultsvalue, HEX);
     irrecvresume(); // Receive the next value
    }
}
Step 5: Open the serial monitor
 
Connect the Arduino to your computer using the usb port, then upload the sketch Open up the Serial Monitor, get the remote and press the buttons Some hex codes should appear on the Serial Monitor
Step 6: Record button codes
  Step 7: Works on any remote!

automatically reducing the output voltage
2Short circuit protection: there is (input 40A fuse) double short circuit protection,
use more secure
 
When using the boost power supply should pay attention to the following points:
1 input power supply voltage must be above 10V
2 when the power supply is used for the input power supply, the input power and
the output voltage of the input power supply are the first to be unloaded Then pick
up the load (must ensure that the switching power supply has been working)
3 when the constant current mode is used to set the voltage, the constant voltage
must be higher than the input voltageDo not use the way of short circuit output current,
the circuit structure of the boost module can not be adjusted in short circuit way
 
Package include:
1x1200W boost constant current module

Tips:
This module can realize the mutual conversion between TTL signal and RS485 signal, but 485 is half-duplex communication This communication mode can realize two-way communication, but it can not be carried out in two directions at the same time That is, each end of the communication channel may be the transmitting side or the receiving side, but at the same time, the information may have only one transmission direction
This module realizes the mutual conversion between TTL signal and RS485 signal, no need to "receive - send" control, use this module as you operate the serial port as simple, compatible with 33V and 50V power supply, compatible with 33V and 50V signal; Imported chip, the performance is very stable, to industrial design standards; anti-interference ability, while more effective 485 mine design, in the industrial field and field harsh environment, the transmission distance of up to 1000 meters Of the 850 meters of 2 * 15 cable to do the test, it is recommended to use within 800 meters, more than 800 meters, please add repeaters)
 
 
Product Features:
Fully consider the 485 bus lightning protection design and anti-jamming design, long-distance transmission in the field, the module's "earth" side access to the earth, can play a very good anti-jamming and lightning effect, 485 Bus more secure; indoor short distance transmission can not access the earth
The use of standard 254 pitch design, to facilitate your secondary development
With 120 ohm matching resistor, shorted R0 to enable matching resistor, long-distance transmission of the proposed short-circuit
Support multi-machine communication, allowing access to up to 128 devices on the bus
Support hot-swappable, there will not be other 485 chip hot plug signal plug dead phenomenon
Large area of copper, to prevent signal interference
Half-hole process design, thickness 08mm, can be easily used as a mother board, but also welding terminal use
With RXD, TXD signal indicator
 
Product parameters:
Operating voltage: compatible with 33V and 50V
Support baud rate: 110-256000bps
Operating temperature: -40 Celsius to 85 Celsius
Communication signal: compatible with 33V and 50V
