Hello
I am doing a project where i want to connect a microprocessor to my DVD player. The goal is to turn on the DVD player, eject tray etc. without using the remote control, but by programming the microprocessor to do so. I have taken the DVD player apart and located the IR reciever [ TSOP4836ZC1 - datasheet http://www.vishay.com/doc?82090 ]. I want to connect a wire from the microprocessor to pin 1 [OUT] on the IR reciver and create the same signal as if you press a button on the remote control, but this seems to be quit troublesome.
I have connected ground from my oscilloscope to pin 2 [GND] on the IR reciver and the probe is connected to pin 1 [OUT], when i do not press any buttons on the remote control pin 1 [OUT] is high +5V, if i press "Eject Tray" a square signal is generated. My problem is how can i get pin 1 [OUT] to drop to 0V to be able to generate the square signal with the microprocessor?
When i first go the idea to this project i thought that pin 1 [OUT] would be 0V when no buttons where pressed, because then it would be quite easy to genereate the signal with the micropressor.
I anyone has ideas, suggestions etc. to get me back on track i would really appreciate it.
Thanks
