ENSURETHATALLCOMPONENTSAREDISCONNECTEDFROMTHECOMPUTER.YOUCANNOWBREAKAPARTYOURLILYPADPROTOSNAPDEVELOPMENTBOARDJBECAREFUL!!!!!THELILYPADCOMPONENTSAREVERYSMALLANDCANBEEASILYLOST.

SewingDirections:

1. UsingtheindividualcomponentsfromtheLilyPadProtoSnapBoard,arrangethemonthefeltpieces.

2. Usingmarkers,sketchthestitchingoutonthefelt.(Redcanbeusedforpositivestitchingleads–blackcanbeusedfornegativestitchingleads).

ImportantInformation:

a. PositiveportsonthecomponentsneedtobeconnectedtothevariouspinsontheLilyPad.BECAREFUL!!!!!Positivestitchesfromoneportcannotcontactpositivestitchesonanotherport.

b. NegativeportswillbeconnectedtothenegativeportontheLilyPadtocreatethegroundofthecircuit.NegativeportscanbeconnectedinonecontinuouscircuitordirectlytothenegativeportofontheLilyPad.

3. Aftermappingoutthecircuit,sewthecircuitcomponentstogether.

4. Onceallsewingiscomplete,checkthestitchingtoensurethatnoconductivethreadpiecesaretouching.Ifneeded,usehotgluetosecurestitchingtofelt.

CodingDirections:

1. Youmayuseanyofthecodingstructuresfoundathttps://github.com/gilescountystem

2. Developyourowncodetocontrolthecomponentsofyour“SmartSuit.”IfusingcodesketchesfromtheGitHubaccount,checkthatpinnumbersforcomponentsarecorrect.

3. Oncethecodeiswritten,verifythecodetomakesuretherearenomistakes.Iftherearemistakesgobackandfixthoseandthenverifyagain.

4. Whenyouareabletoverifyyourcodewithnomistakesandthecircuitsaresewntogether,uploadthecodetotheLilyPadArduinoandseeifcomponentsworkproperly.
