The IR-Sensor signal pin is an 'active-low' signal. This means, you need to tie this signal to +5 through the 1K ohm resistor. When the IR-Sensor detects a signal, it will then 'pull' the pin low.
Alternating 1's and zero's indicates the pin is 'open', acting as an antenna.

i connect the ir sensor signal pin throught a 1k ohm and the transmitter throught a 220 ohm.
