In addition, a simple pushbutton switch is used to send the last code saved to the dvr.

If a camera has 940nm infrared leds it will be labelled as such in the description. The voltage across any forwardbiased led any diode, really will be governed by the diode, and will only vary slightly with current. As with any led, you should be concerned with the led current, much more than its voltage. The next stage is to connect the ir led and resistor to the arduino board. Adafruit metro 328 fully assembled arduino ide compatible. Arduino code ir sensor infrared ir led 5mm 940nm detection. So, to send signals that the ir receiver can detect, your arduino will have to flash the ir led onoff at 38 khz. You could use an ir receiver which we carry to clone the signal from a normal remote like your tvs and use this led with a development board like the arduino unowhich we carry.

Lirc is a software that allows you to decode and send infrared signals of many but not all commonly used remote controls. If you want to drive an ir led properly, consider using the ir led with a transistor and resistor that was used in the design of the old sparkfun max power ir led kit.
