-ots o' space in there. he arduino is bolted to the etal base plate he shield is only there to provide a stron0 attachent point 'or the wires n'ortunately, 2 only had solid core bell wire, so

the cablin0 is uite sti'' and hard to work with 3e+t tie 24ll use ribbon cable.

5urried under the wires are two 627 resistor packs he -E8 pack is !9 ohs 2 would have

liked : ohs hey would be uch bri0hter then 5ut 2 didnt have any in y inventory, anddid not want to solder individual resistors ;oon pin on the 627 0oes to 0round 8i0ital

outputs on the <rduino send current throu0h the -E8, then throu0h the 627 resistor pack

he 5uttons are ounted in seperate bo+es hey are typical arcade style 2 was 'ortunate to 'ind

a local shop with % colors Each button has a lon0 cable (at least : eters) so that 2 can use thiskit in a school classroo he player 0roups could be pretty 'ar 'ro the ain bo+

5uttons are tied hi0h with another 627 resistor pack 2n this case, the coon pin on the 627 is

connected to : volts he resistor output is then tied to the analo0 inputs (2 a usin0 the as

di0ital inputs) <lso tied to the input is one le0 o' the switch (via the R;< connector on the bo+)he other end o' the switch is connected to 0round When the switch is open, current 'lows into

the input, re0isterin0 a &2=& value in so'tware When the switch is closed, current takes the path

o' least resistance, 0oin0 stri0ht to 0round, rather than enterin0 the <rduino input pin heso'tware reads this as a ->W condition

2 have space in the bo+ 'or 'uture up0rades 2 plan on installin0 a ?correct? and ?incorrect? button

on the head unit, as well as a reset (so 2 can bypass the : second tier)

2n addition to winner deterination, the so'tware also provides a serial essa0e output 2 hope to

eventually connect it to a 7; and write soe 0aeshow so'tware
