    Note: Depending on your Ardunio IDE version, you mayfind it useful to turn on the “Display line number” function for your Sketch Software. Click on the File >pull down menu, then click on Preferences. In the the pop-up Window, check the Display line numbers box, and then click on the OKbutton. Now each line of code inyour Sketch Software will have a line number. The Edit > Go to line…feature may also be of some use in navigatingyour Sketch Software.

    A quick note about the two Sketch filesLine number 76 in the Sketch is where you set your true/false codeconst boolean IS_METRIC = true; //set to false if you prefer imperial/inches, Fahrenheit

    (Original post had a few errors, here is a corrected version)Here is a pictorial Schematic of this project; I like to work from aschematic myself, it gives me a good understanding of what I am doing. I put thistogether and thought I would contribute. Thanks sjoweet, this is a great little project, I have my material on order (it will take several weeks, coming from China)

    Solid-State Auto-Reverse for Camera Slider

    Note: Quick update... on the schematic and wiring diagram I left off the RC differentiator that goes between pin 3 (chip A) and pin 2 (chip B, the Timer). You need this so that the signal from chip A is only a momentary negative spike to the timer, else the ckt will stay in the pause mode while the micro switch is pressed.

    Very nice... makes for a great "look see" at the simplicity that can be achieved with a little reflection on the given project. Thanks for sharing.

    Garage Door "OPEN-CLOSED" Indicator

    I'll leave that one to someone else...

    IMO it's all about placing an Indicator "of some type" in the Bedroom to indicate that the Garage Door is open or closed!!!! We can all talk about this or that design... but the real prize is the peace of mind, at feeling reasonably assured that the "Door is Closed" when we look up at the indicator!!!

    Interesting design, and it does use very, very few parts. Personally I would just use a CMOS Inverter that would consume less power vrs a Relay. The use of a mechanical device vrs a Digital device (IMO) tends to introduce a less reliable functional Ckt... but that's just me. Yet many of today's PCB type of Relays are very reliable. P.S. I am also trying to figure out how to attach a sketch drawings... but I see you got it to work. Very good!!!

    Garage Door "OPEN-CLOSED" Indicator

    Yes Sir...the two Transistor Ckt was my first draft and it worked well on the breadboard,although in my case I used the 2n3904 NPN (seems to be more common and veryinexpensive in North America). Anyway, I wanted something a little more elegantand creative in the CMOS digital world... thus I went with a spare NOR gatethat I had on hand. The use of a 7404 or 4049 would probably make for thesimplest Ckt with the fewest parts (two LEDs, two Resistors, and one IC), but Idid not have any of these ICs on hand. As referenced before... there are many,many ways to make this simple logic Ckt. Overall...my driving purpose here was a Garage Door Indicator for the Bedroom... with thematerial I had on hand. At the same time it's fun for the Hobbyist, like me, tosee how creative I can be with the parts...

At the same time, an elegant and creative design (IMO) does not always mean a design with the fewest parts, although that can be a rewarding goal for a Ckt design at times.If you have the time, I would very much appreciate your design ideas for a proven Ckt with the fewest parts, be it with Transistors or ICs. I wounder if this could be done with just Resistors and Caps??? Now that would be an interesting design.

    Garage Door "OPEN-CLOSED" Indicator

    Yes, you are correct; there are a number of ways to achieve thissimple logical function, just alternating between two LEDs based on the stateof a switch. I had the CM4001 and the Wall-Pack in my parts bin, and being a low power CMOS, that is what I used. I would encourage, evenchallenge, the more technically inclined to look in their parts bin to see howthey can use what they have to get the same function without having to buy tomany additional parts. In my case the only thing I had to buy was the 100' of 4wire cable (what can I say I have a lot of electrical and electronic type ofjunk in my garage!!!). My unit has been up and running for about two year now,wrote up the WORD file about the same time, since then I switched out the ACWall-Pack with a 15v DC Power Pack. But its just a matt...
