Today I have done some serious tests with some oscilloscope and other sensitive gear. And I realized That The laser in fact is fast enough to reproduce a frequency of 1000 Hz but that frequency is creating a very low voltage ( 1-1.5 V) at the receiver diode and the Arduino does not recognize...

Thanks I will try to do that. :thanks:

Thank you very very much. All of those information were quite useful and i learned some things. But i am trying to send data from one computer with the laser at some speed and testing my green laser i revealed that it doesn't fully light up at frequencies higher than 200 Hz. The laser as you...

First of all thanks for the fast response. The project is rather complicated and I am doing the hardware and my friend is doing the software. The project is based on transferring data between two computers with a laser. Now let me explain all of the details. The receiver is based on an Arduino...

Hello I'm new to the forum so i hope that I'm not doing something wrong. But here's my question. I am building a laser setup with an audio control. The laser has to be turned on and off with sound coming from my audio jack on my PC( max. 20 000 Hz). I understand electronics pretty well but this...
