queries on arduino remote

i have a project on IRremote controlled laptop on arduino uno. i hav clear program and upload it..there was no error in that. IR receiver receives the signal and display the output codes on serial monitor COM3 .but i dont receive correct output... please see my attachment.thnk u

Anyway, what IR protocol are you using (NEC, Sanyo, Sony,…?)

The IRremote library depends on several things in order to properly decode a command:

  • Proper mark and space pulse width in milliseconds
  • Presence of the initial header (typically a longer pulse of 2X normal width)
  • Proper number of bits in the command
  • Proper IR carrier frequency (usually 38 or 40 kHz)

Also, what are you using to RECEIVE your IR commands? (Hopefully one of those 3 terminal IR receivers such as a TSOP 1738 or 1740)?

Please post your code (using the code tags - the button on the upper left corner of the editor that looks like [</>]).
