  3. 3. Do  you  know  how  a  clock  operates?  The  hands  of   the  clock  run  in  a  clockwise  direcDon  because  the   motor  runs  in  the  same  direcDon.  Now,  if  the   direcDon  of  the  baIery  is  reversed,  the  clock  will   stop.  This  happens  because  the  diode  is  present  in   the  clock  circuit  which  prevents  the  motor  to  run  in   the  anD-­‐clockwise  direcDon.   In  this  project,  you  will  need  a  resistor,  a  diode,  a   DC  motor  and  a  few  connecDng  wires.  The   connecDons  are  made  such  that  the  resistor  is   connected  in  series  with  the  parallel  combinaDon  of   the  diode  and  the  motor.  AMer  the  compleDon  of   the  circuit,  the  motor  starts  to  rotate.  When  the   baIery  connecDons  are  reversed,  the  motor  stops   to  rotate.  The  two  phenomena  were  reasoned   doing  the  current  path  analysis  in  both  the  cases.   Thus,  the  diode  ensures  that  the  motor  does  not   rotate  in  the  opposite  direcDon  when  the  baIery   connecDons  are  reversed.
  4. 4. Have  a  look  at  what  we  provide  in  our  Project  Kit! CoolJunk   is   India's   fastest  growing  DIY  (do-­‐it-­‐yourself)   kits   company   focused   on   project-­‐based   learning   in   science,  engineering  and   technology.  Having   20,000   users   in   India,  US,   Singapore,   Middle   East   and   New   Zealand,  the  CoolJunk  kits  are  known  for  quality,  innovaDon  and  high  producDon  value.  CoolJunk  has  been   featured   in   naDonal   and   internaDonal   journals   including   Wallstreet,   Yourstory,   Hindu   Business   Line,   NextBigWhat  and  was  tagged  as  the  coolest  Indian  start-­‐up  in  IAN  Bootcamp-­‐2011.   For  more  projects  visit  our  website:  CoolJunk   All  tools  and  components   in  one  box.
