Infrared Burst Length
Hello, wanted to ask a question that google does not seem to be my friend with, what is an infrared burst length? From what I understand its the minimum length that you need to transmit an infrared burst for it to be picked up by the sensor. I am looking particularly at the TSOP4856 I have been in c...

Re: 555 in astable mode (carrier frequency)
no i haven't my application is for a laser tag setup so im trying to get the frequency to be the best match for the diode and receiver to avoid this being a range limiting factor, ive been looking at code for doing this, im trying to avoid using external library's and making the code as optimised as...

Re: 555 in astable mode (carrier frequency)
Hi a lot of people on the forums believe that using another chip would be a better way so now i am trying to use my arduino duemvilanove to generate a 56khz square wave using the method describe here https://www.arduino.cc/en/Tutorial/SecretsOfArduinoPWM however its not making much sense at the mome...

Re: 555 in astable mode (carrier frequency)
I have attached a proper picture below that might help, Thank you i am using a breadboard with jumper wires and they are most probably to long. My application for this is a laser tag set-up so it is a long range application, I have used a 555 timer to generate the carrier frequency as I do not want ...

555 in astable mode (carrier frequency)
Hi all, I am trying to create a astable circuit to generate a 56khz carrier frequency for infrared but first i want to build the astable circuit using a 555 timer i have used the information online using this website here http://www.ohmslawcalculator.com/555-astable-calculator the values i have used...
