You turn it on and off at about 38kHz with an oscillator. A 555 oscillator is powerful enough for it.shaneshane1 said:does anyone know how to modulate a standard infrared led for the receiver
audioguru said:Look at the datasheet for a 555. It has a chart with resistors and the timing capacitor values and frequencies. It also has a formula for you to accurately calculate their values.
The IR receiver you got doesn't have its frequency specified, does it?
No it is not! The datasheet shows 36kHz ones, 38kHz ones and 40kHz ones. Jaycar ripped you off since they are all mixed up.shaneshane1 said:yes its center frequency is 30.0 to 40kHs
