Exact opposite of that needed.OK cowboypop...
When not pressing - pin 14 shows 4.7 V and when pressing .. showing 0 v .. but only for 1 second .. after this again 5 v
Les has a point. The data pulse stream generated by the remote may very well be over whelmng the 4017.... I suspect that C1 may not be filtering out the code pulses properly. I do not like the design of the coupling between the IR receiver and T1. ...
The red LED should be normally be ON. It should go OFF when the green LED goes ON and the relay trips.The output is not coming from pin no. 2 When pressing the button of the remote... and when pressing .. Red led just blinks once..
Actually the tsop1738 has a 100k inside the part, I don't think the external resistor on pin 2 is needed.I would think a 2N3702, 2N3906, BC557 or BC327 should work. While looking at the data on the TSOP1738 I noticed that the maximum output current rating is 5 mA There is nothing in your circuit to limit the output current. I would suggest adding a 1K resistor from pin 3 of the TSOP1738 to the junction of C1+ and the base of T1
