I have a problem.....can you tell me which type of Q3 NPN Phototransistor you used and the function of LM567 Tone Decoder |

You should be making your own topic instead of hijacking other people's posts.
However, to answer your question, a solder pad is simply the pad of copper through which a component lead sticks and is soldered to.
My "How To Solder" writeup is pathetic and rather old. I am making a much newer one currently, but I don't know when it will be online. |

Hello,
Firstly the caps lock is kinda annoying, like you're shouting the question at us and secondly its in a very wrong place.
But to answer the question, a solder pad is just the location on the board you will be soldering the component to. Generally a circular small piece of copper with a hole in the middle... You could just google it. |

The circuit can be used with any general remote.
Check the link for more info. It contains the explanation and schematic.

help me. I want to make simple remote IR that consist of 2 buttons, first button to activate the device, and second button to deactivate the device. any component that will I require? there is again, I wish that remote can be functioned at a distance of around 10 metres or around 30 feets. |

Most NPN photo-transistors are the same. A few are more sensitive.
The LM567 detects the frequency that modulates the IR LED so that interference from lights doesn't trigger the relay. |
