It probably should not be longer than about 3 or 4 paragraphs. For example: This report describes how two common digital integrated circuits (ICs), the 7490 decade counter and the 7447 decoder, a photointerrupter switch, and a seven-segment light emitting diode (LED) can be used to produce a simple counter. We built a counter from a schematic diagram given in the instruction sheet for this experiment. We demonstrated its successful operation by cycling the count from 0 to 9, several times. So on and so forth! Results/Discussion Describe what you did in the lab and what your results were. Include enough figures, tables, and/or description of what you did, so that someone who is unfamiliar with the lab could repeat what you did. (Note the figure caption below. All figures must be numbered, have a title, and have a descriptive sentence or two explaining the significance of the figure. See the  HYPERLINK "http://www.engr.sjsu.edu/bjfurman/courses/ME120/me120pdf/ME120labreportguide.pdf" ME 120 report writing guide for more information about figures and tables.) This section must answer the questions, What happened? Do the results agree with what I expected? Why or why not? Also answer any questions posed in the instructions for the experiment. Try to work the answers into the flow of this section. For example: We built the counter according to the schematic diagram shown in Figure 1. The circuit did not function at all until we discovered that we wired the wrong pins from the photointerrupter to the 7490. We corrected that problem, and then we discovered that the 7-segment LED did not indicate correctly when we reached the count of 2  EMBED Word.Picture.8  Figure 1. Counter display circuit. Each time an object passes through the gap in the photointerrupter, the count is incremented by one. The decoder takes the count and turns on the proper LED segments to display the number. So, if the lab manual asks the question, Why is the sky blue? Dont restate the question verbatim in your report, just work it in to the narrative. We determined that the sky is blue, because So on and so forth! Conclusions and Recommendations Put your conclusions and recommendations for what should be done with what you learned in this section. The conclusions should be your reflection on the major results from your experiment. What happened, and what are the implications of what I learned in this lab? What can I do with what I learned here? etc. Try to be specific in what you write. For example: We found that a photointerrupter can be used as a switch. It has important advantages over mechanical switches in that no physical contact is needed, and it does not need to be debounced This experiment demonstrated the basic principles and components involved in digital displays and counter circuits We recommend that voltage measurements be taken at pin 7 in addition to ... So on and so forth! Dont forget page numbers, references, etc. For more information on how to cite references, see the ME 120 report-writing guide at:  HYPERLINK "http://www.engr.sjsu.edu/bjfurman/courses/ME120/me120pdf/ME120labreportguide.pdf " http://www.engr.sjsu.edu/bjfurman/courses/ME120/me120pdf/ME120labreportguide.pdf      PAGE 2 PAGE 1 San Jos State University Department of Mechanical and Aerospace Engineering +y  ' g h bcz{|}~^#679XDWXп䞔x h F<CJ] h F<6] h F<>*CJ h F<5CJjh F<CJU,jtN: h F<CJOJQJUVmHnHujh F<CJU h F<0Jjh F<Ujh F<Uh F<56\]^J h F<CJhq h F<CJh F< h F<5CJ-+EYgy' b~^ Fu]^F`ux $ N dxa$ *h]*^hh`hd@& d` dx`  dx`$ d&dPa$^#79YDX N hd`h vh]v^hd@& $ N da$ *h]*^h$$&h]&^h`h`hX=>? ſŴſſũſ h F<CJhq0JmHnHuh F<0JmHnHu h F<0Jjh F<0JUh F<jh F<Uh F<0JCJjKh F<CJUjh F<CJU h F<CJ# $a$$a$$h]ha$h]h&`#$=0 P@PBP/ =!"#$%@@ DpDyK yK http://www.engr.sjsu.edu/bjfurman/courses/ME120/me120pdf/ME120labreportguide.pdf8Dd 1 B  S A? 2&KU br~W `!v&KU br*w@O`!Dx tՙǟ{RXPh I֏t9-Eϩh|ujaHJrDcZmYY zR Ŷ癹7ws^&<{s#\)ܰf4E]+V6,]UF0>B7觑u? mGHBeCA7E kr+ZZ )`:wR(P')& $J5ѷ]=.?c;Wcp6ofZds\]("r:@8W1 `pr1A,QfM1,e)\fkDY5 GibběM/9ᚆ#411EtJ ĭP#9l?i8HSD'sMMpMyUєk,44q{q{xWnMG":i~VwqwqwxY/N٪(FJG"SDGi%/GVi8H3Sds -__h8H3Sds Qb)Wi8m2Sds oVl`kEp̑&f 6oDy=1e.4s)2y j9,֧*l0מRa*̙\wfV|ؙ\2|P9;kO*g_V*l+la]"L戰̜ug~nU·ɵ+Cs3dr 3RaTVXVLV*̙\wfV|ؙ\2|P9;kO*gVV֨ k1uXa[3UX03grݙ[acgrʐAkL=r>2Xa2U.UaVC*YU3ϭ3ver5v&מ 9UTa{ +l+V؞LvLU9 ;v&SDU3ϭ3ver5v&מ 9UTa' +V!;Gǻmyz|\kC~xԾ7ݛ;:əΪlOBp凣|㱰u~c'ƞq:nU/z[]oUܧͶ*^ߪș*r6۪:R~"yl ^(g;[9Rf[Gvz*r>Ͷ*o#J<9;e+t[ΟW?7sc&ʹft935g$9~P\ ﯭ'8Na]r7g;{_42&&)b6hcޜΛl8O.X&6-M5p ~`LݚW?5v&r>ؙ\Od-[\3þN\!jw-OZ+9t[잠Yp{H@S$ t>CkQ0̰\.Ws~^3r&ijƾj;݅p;:}Xp}iEl61daÚ'Ng&3 ڽf24|Ĉ"[ţF <7y0jT}Y2MÿYfs"np:#ʠÍIZn4yK)b 9цg~O8;5 b؞{G&ok~yK)bydg4s["z+WØĎtvXj8щ?+qH4MG":]X/YkDSYxx~@WW&k,7VUѢiw&":qB=-[opV":RXfP6>i8Cym|(w[3Pwgٻj5 `b޻!_!6ċ5 Gibb޻'v]M;? xYXRMÿ1El~!.;Yvdч}J_8 Q틢/,|MG"nVEGȓUA{[d3QSݸ7;(#MK5 %)ςq&zY5 ?MSD'm ] !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ_`abcdefghijklmnoqrstuvwyz{|}~Root Entry  FP q.\Data ^WordDocument ?"ObjectPoolp.P q._978253428 Fp.Bp.1TablezCompObjhObjInfo [(@(NormalCJmH <A@<Default Paragraph Font0 @0Footer  !CJ,@,Header  ! #'+/37;?DKPUX[^aeimptx{  128CU^m\     wxz{|}~S #'+/37;?DKPUX[^aeimptx{  128CU^m  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\" \v\ 1c\ dz[ l,2$ofn9]>dGhoI@*ON( PU x  < x  < x  < x  < x  < x  < x   < x   < x   <   x   <   x   <   x  <   x  <   x  < x  < x  < x  < x  < x  < x  < H  C 'H  C 'H  C 'BB  3 'BB  3 'BB  3 'BB @ 3 'BB  3 'BB  3 'BB ! 3 'BB " 3 'BB # 3 'BB $ 3 'BB % 3 'BB & 3 'BB ' 3 'BB ( 3 'BB ) 3 'BB * 3 'BB + 3 'BB , 3 'BB - 3 'BB . 3 'BB / 3 'BB 0 3 'BB 1 3 'BB 2 3 'BB 3 3 'BB 4 3 'BB 5 3 'BB 6 3 'BB 7 3 'BB 8 3 'BB 9 3 'BB : 3 'BB ; 3 'BB < 3 'BB = 3 'BB > 3 'BB ? 3 'BB @ 3 'BB A 3 'BB B 3 'BB C 3 'BB D 3 'H2 E C 'H2 F C 'BB G 3 'BB I 3 'BB J 3 'BB L 3 'BB M 3 'BB N 3 'BB O 3 'BB P 3 '~BB Q 3 '}BB R 3 '|BB S 3 '{BB T 3 'zBB U 3 'yBB V@ 3 'xBB W@ 3 'wBB X 3 ' BB Y 3 'vBB Z@ 3 'uBB [ 3 'tBB \ 3 'sBB ] 3 'rBB ^ 3 'qBB _ 3 ' BB ` 3 'p BB b 3 'o BB c 3 'n BB d 3 'm BB e 3 'l BB f 3 'k BB g 3 'j BB h 3 'i BB i 3 'h BB j 3 'g BB k 3 'f BB l 3 'e BB m 3 'd BB n 3 'c BB o 3 'b BB p@ 3 'a BB r@ 3 '` BB t 3 '_BB u 3 '^BB v 3 ']x w <\ x x <[ H y C 'Zx z <Y x { <X x | <W x } <V x ~ <U x  <T x  <S x  <R x  <Q x  < P  x  <!O !x  <"N "x  <#M #x  <$L $x  <%K %x  <&J &x  <'I 'x  <(H (x  <)G )x  <*F *x  <+E +x  <,D ,x  <-C -x  <.B .x  </A /x  <0@ 0BB  3 '?BB  3 '>BB  3 '=BB  3 '<BB  3 ';BB  3 ':BB  3 '9x  <18 1BB @ 3 '7BB  3 '6x  <25 2x  <34 3x  <43 4x  <52 5x  <61 6x  <70 7x  <8/ 8x  <9. 9x  <:- :x  <;, ;x  <<+ <x  <=* =x  <>) >x  <?( ?x  <@' @x  <A& Ax  <B% Bx  <C Cx  <D Dx  <E$ Ex  <F# Fx  <G Gx  <H" Hx  <I!
