Hello friends!.this is gonna be my first instructable and so pretty obvious that this is gonna be my first contest . I am Shreeman ,14 and i have just made a pretty pair(not exactly pretty if you know what i mean)of shoes,one for my father and one for my sister.
one of the is where the laces automatically tie.And the other one is where you have bright green-red led colors.pretty simple if guys like me can build it and it sure is a good base for you to learn soldering too.
i am participating in the footwear contest,and i have pretty much just a few hours left.so if you like it please vote for me.Yeah and you know itwill do well atleast untill Nike hypershoes come.
since there was not much of money and space left i made it in 2 shoes and made only for one in each pair.
So lets get started!
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: PARTS AND TOOLS!!!
Tools: soldering iron, screwdrivers, etc. A USB A to B cable and a computer to Sketch the Arduino.
A shoe -so i used 2 shoes here but if you have space ,you could fit it in 1
Force sensor- got mine on ebay
Servo Motors - again on ebay
Arduino -just the UNO
LED and a couple of resistors- found them under my bed!!!
copper wire -tore from a old computer
Plastic zip ties-remember size is the main constrain.i ordered a wrong size and gotta reverse that
Step 2: Mounting Him Up!
So next is the mounting part.now what I did is that I attached the servos to the back of the Arduino board and then to the shoe. Pretty easy-wheezy right? NOT AT ALL! (ATLEAST FOR ME).
what I did first is I started drilling it .but the hole becomes too wide.so manual drilling with a screw driver and then pulling some
fishing strings in and out. At last after some 10 ties it was well fit up there.
The Motor Shield enables the Arduino to control the 2 servos
I got an L239D model.
Following the instructions on the next step, solder the Motor Shield together and attach it to the Arduino via the header pins.
Zip ties are used to mount the various electronic components.
The motors were attached to the mounting plate first by using some rubber cement (optional) to keep them in place, and wrapping and tightening them as much as possible with the zip ties.
Note that most of the ties thread through the space between the mounting plate and the shoe. As my zip ties weren't long enough in some areas, I combined two together. After the servos were in place, I trimmed down the ties.
Beneath the motors, the battery case is mounted in much the same way, power switch outward.
Finally, the Arduino board can be attached. The holes line up with zip ties on both side, and is held in place by screws attached to them.
Before attaching the Motor shield, some modifications must be made.
Step 3: Soldering Time!!!!
First, we solder a resistor and to one pin of the LED and a length of wire to both pins.
That assembly is then pushed through an small pocket thing, and the wires are ran to the Arduino, using hot glue to keep everything in place and out of the way. Make sure you know which of the wires goes to the positive pin of the LED!
The Force sensor is mounted next. since it will melt easily, I took some alligator clips and covered the plastic part.
The wires which will be connected to the shied and the servo wires can be tied together.
then a resistor, soldering wires and copper wires are needed. Much of this information is from an other project maker.
1. The positive wire of the LED goes to digital pin 2.
2. One force sensor wire (doesn't matter which) is soldered to +5v.
3. The other force sensor wire goes to Analog Pin 0.
4. Also connected to Ana. Pin 0 is a resistor. The other end of the resistor goes to Ground.
5. Also connect the negative LED pin to Ground.
6. A four inch spiral wrap of wire is soldered to Analog Pin 5. This is the touch switch- touching this wire firmly will cause the servo motors to move into the unlocked position.
7.Then the servo motors need to be attached. Remember the adjustments vary from shoe to shoe.
Step 4: Hook Up the Laces to Your Servos!!
Now is the tricky part. The laces . I made 2 on both sides and hooked them to the opposite servos.They were connected using zip ties.
I fastened them together and made sure they wouldn't fall off.
Step 5: Code It Up!!!!
Yes yes, The usual!!.set up a power connection. The to the computer and then upload it.that is all.make sure you select the right port and there should be enough power for uploading it.make changes as you feel.
The code is as follows here. Hope you enjoy doing it. Thank you for reading this
Step 6: The Colorful Part
now this step is plain simple.just take an led strip.cut it into your required dimension based on your shoe size and you could use either double sided tape or a glue gun to stick it. I would prefer tape in the place of messy glue.then you connect it to a 9v battery and make a small pouch for that.Voila ,you are done.YAAAAAAAAAAAAAAAAAAAY!!@SHREEMAN
