Current consumption depends on power supply and duration as S1 remains pressed. Bright light will stop the receiver from responding to the transmitter. It had excellent handling characteristeics, and the response to the sticks’ was appropriate and proportional (not over or under-responsive.) So I am going to make ir transmitter and Receiver using NEC Protocol that can be used for various purposes. The 555 Timer IC operates in an astable mode. Also it's possible to replace the pot R1 with a", "I made the circuit, it works great, but in the lowest level of POT there is still 50V on the load", "You can actually take infra-red pictures with the average video camera. The IR phototdiode is sensitive to the IR light emitted by an IR LED. I guess when you buy a 4 channel copter for under $50, you have to expect that they’ve tried to save money somewhere, and their production quality control standards is where they apparently cut back on costs. There are five push buttons in the circuit, each push button sends a different IR code via an IR transmitter. By using this Circuit, we can increase the range of emitted IR radiation up to 100cm. By the way, as this new/2nd heli ‘used to’ have the nice ‘proportional responsiveness’ to stick movements as the first version, this ability seems to be deteriating over time. This IR transmitter sends 40 kHz (frequency can be adjusted using R2) carrier under computer control (computer can turn the IR transmission on and off). $9.90. 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. The first example circuit uses a TSOP382 IR photo sensor to receive and demodulate the IR signal from a common remote control. Then the IR LED emits the light of some frequency. This project explains the principle of IR communication. Similarly to the receiver, the hardware required for transmitting IR input is reasonably simple. $7.99. How IR Remotes and Receivers Work.
