STEPSForDesigningSewnCircuits
1. Considerwhereeachcomponentwillbelocatedinrelationtoothercomponentsthatwillbeused.
2. ConsiderwhichpinswillbeusedforeachcomponentontheLilyPadArduino
relativetoothercomponentsbeingused.3. Decidewhatsizepieceoffeltwillbeneededforyourdesign–testthefeltpiece

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.
