    Find the ground wire. Find a suitable spst switch. Install the switch in between the lead coming off the pin and the actual ground.

    Pickit 3 vs Arduino uno

    Ive decided to go with the arduino uno. No kit. Ill probably try others down the road as i am very interested in the "raw" feeling of programming in assembly

    Salvaged components

    Try a 555 timer circuit. Alot to take in at first but after a day of playing with it, theres nothing to it.

    Help finding a switch

    I think most leds can handle 3v just fine anyways. Provided the button cell you are using is a 3v cell

    Experimental Repair

    Yes im sure i made another post about this project. I like the light idea. I may try that. As far as the noise maker. I already bought the ic. I would like to put it to use. Heres the pir sensor. Its cheap but...

    Experimental Repair

    I have learned a good deal more since this post. This "repair" was a broken gun at work. Obviously it didnt work. As far as the set screws stripping. We usually just drill and tap a 1/4-20 hole in the other side. Works pretty good. I am actually working on a motion alarm project right now. A...

    Pickit 3 vs Arduino uno

    Arduino is starting to sound better. Do i still need a programmer? And is the uC soldered in? Or is there a socket?

    Pickit 3 vs Arduino uno

    I realize this is going to start a massive argument.... That being said, im torn between the two. Im leaning towards pickit because im not sure you can use different uC with arduino. Only the one that comes with it. I want to be able to use a variety a controllers. Correct me where im wrong...

    I think thats a good project. That transformer shouldn't be too hard to find. Keep the us updated!

    Salvaged components

    Im working on a motion alarm right now. Its kind of a struggle when you have salvaged parts. Especially when you need a certain value and its not there

    Salvaged components

    Has anyone actually built anything useful with salvaged material? Im trying to find a "Frankenstein" type something to build out of all my junk

    What is this?

    You know what thats it! I did tear down an old computer monitor awhile back. Thats awesome you found it. Great researching thank you!

    What is this?

    Well i guess it really is a mystery then. I may be told told to make a new thread but since i have you all here... I am having problems with a PIR sensor. I have 7.5v going into it. And the output is going to an LED and then finally to ground with the PIR ground. The output of the sensor is...

    What is this?

    If it didnt have so many pins i would just start hooking up wires and measure with multimeter but i don't want to damage the chip. If it helps it says" Taiwan F9KC7P1" on the underside.
