Arduino-Based IR Translator (SONY)
DESCRIPTION
This arduino project utilizes the Arduino Uno board to record IR signals and translate from one signal to another. The result is a module that converts any remote into a universal remote.
Materials Needed:
- 1 Arduino UNO
- 1 IR receiver module
- 1 IR diode (940nm)
- 2 LEDs (Red, Green)
- 1 Momentary Push button
- 4 Resistors ( (3) 220ohm, (1)10kohm )
- Wires
*Current version only supports SONY output signals. Any input may still be used.
Connect the IR sender LED:
- (+) leg to digital pin 3 on Arduino (native pin for IR output)
- (-) leg with a 220ohm (not shown in diagram) resistor to Ground
Connect IR receiver Module:
- pin0 connects to Ground (left)
- pin1 connects to Power (middle)
- pin2 connects to digital pin 11 on arduino (right)
Connect Button:
- Bottom right pin connects to Ground
- Bottom left pin connects to Power
- Top right pin connects to digital pin 8 on arduino
Connect the red LED:
- (+) leg to digital pin 9 on Arduino (native pin for IR output)
- (-) leg with a 220ohm resistor to Ground
Connect the green LED:
- (+) leg to digital pin 10 on Arduino (native pin for IR output)
- (-) leg with a 220ohm resistor to Ground
- Wire together the Power and Ground Rails on bread board
- Wire the Power and Ground rails on board to Arduino +5 and Gnd pins
Upload the code to Arduino.
Notes:
Sony IR protocol uses a signal burst of 3 repeated codes with a delay of 10ms between each code
The current Sony signal output uses 20 bit codes. Modify program-code to change the bits.
- Ex. irsend.sendSony(code, 20); CHANGE TO irsend.sendSony(code,12);
- Use example IRDumpv2 code to read code specs
