When Ub = 2V, the frequency is 29.3 kHz, the LEDs top current is 25 mA and total current consumption is 27 mA. After that, the receiver then demodulates the signal. The second example circuit uses a 950nm IR LED and current limiting resistor to transmit IR codes to a common appliance, for example a home stereo or TV. They are mostly simple and cheap devices. As the switch is pressed, the connection between an IR LED and the 555 timer IC closes. The 555 Timer IC operates in an astable mode. This device reads an infrared signal modulated at 38 kHz and de-modulates it into a clean square wave so that a project can detect the patterns sent by an infrared transmitter such as a TV remote. But with this Drift King, apparently, someone at the big C factory had barely inserted the tiny gear sufficiently onto the main motor’s shaft, and one little bump of the helicoter caused it to dislodge.
