Iibhodi ze-Breadboard, ii-Screw Terminal, okanye iiKhebula ze-Modular: Yiyiphi iNkqubo yokuFaka iiWaya eNokumelana neBanga lesi-7?
Iibhodi ze-breadboard zichitha uninzi lwesifundo semizuzu engama-45 seBanga lesi-7 zikhangela iiphini ezixegayo. Nantsi indlela iiwaya ze-jumper, ii-screw terminal, kunye neekhebula ze-modular ezinamaqhosha ezithelekiseka ngayo ngokuhlala ixesha elide, indleko, kunye nokulawuleka kwegumbi lokufundela.
Kwiklasi yekhowudingi nerobhothiki yeBanga lesi-7 enabafundi abangama-35 ukuya kuma-40, iikhebula ezikhiyelwayo ze-modular (ezifana nezihlanganisi ze-Grove okanye ze-JST) kuphela kwenkqubo yokudibanisa ekwaziyo ukumelana ngokuthembekileyo nokuphathwa mihla le esikolweni. Iibhodi ze-breadboard ezingenantengiso kunye neewaya ze-DuPont jumper ezingabotshelelwanga zinika inkululeko entle kwinqanaba lamalungu kubafundi abadala, kodwa kwiiklasi zabaqalayo zasebancinci, zithatha uninzi lwexesha likatitshala ekulungiseni iimpazamo zangaphakathi ezibonakalayo endaweni yokufundisa ukucinga ngokwekhompyutha.
Ukubalwa kweXesha lesiFundo seMizuzu engama-45
Cinga ngolwakhiwo lwesiqingatha sexesha sesikolo saseMzantsi Afrika. Xa abafundi bengena, bevula iikhompyutha zabo kwaye befumana imiyalelo, ixesha lokusebenza ngezandla alidla ngokugqitha kwimizuzu engamashumi amabini ukuya kwamashumi amabini anesihlanu ngaphambi kokuba kuqalwe ukupakisha. Ukuba utitshala ujonge amaqela alishumi anabafundi abane, ukuchitha nokuba yimizuzu emibini kuphela kwiqela ngalinye kulungiswa uxhulumaniso lwe-breadboard olungazinzanga kuthatha lonke elo xesha lomsebenzi wezandla.
Ingxaki ayikho ekubeni abafundi beBanga lesi-7 abakwazi ukuqonda isekethe yombane; yeyokuba iibhodi ze-breadboard zingenisa iingxaki zomatshini ezifihlakeleyo abangakwaziyo abafundi abancinci ukuzibonela ngokwabo:
- Iphini le-DuPont elifakwe kumqolo ongeyiyo kwibhasi yangaphakathi (umz., umqolo 14 endaweni yomqolo 15).
- Isokethi eyi-female jumper exegayo eyenza uxhulumaniso phezu kwedesika kodwa icime ngalo mzuzu isiseko serobhothi sishukumayo.
- Iphini eliyi-male eligobileyo elaphukela ngaphakathi kwi-header ye-Arduino okanye ye-micro:bit breakout, nto leyo eyenza ukuba loo ndawo ingasebenziseki kwiklasi elandelayo.
- Iisekethe ezimfutshane (short circuits) ezenzeka ngempazamo kwiintambo zombane xa iintambo zitsalwa ngamandla ngexesha lokupakisha.
Xa ikhowudi yomfundi isilela ukukhanyisa i-LED, injongo yokufundisa kukuba baphonononge ingqiqo yabo, ii-loop, kunye nokwabelwa kweephini. Xa i-80% yeempazamo ziziphazamiso zocingo ezixegayo endaweni yeempazamo zekhowudi (bugs), abafundi bakhawuleza bafunde ukuxhomekeka kwabanye—baphakamisele utitshala izandla endaweni yokuba bazilungiselele ikhowudi yabo.

Ukhetho 1: Iibhodi ze-Breadboard nee-DuPont Jumper
Iibhodi ze-breadboard zihlala zikukhetho oluqhelekileyo lwabantu abenza izinto zokuzonwabisa kwihlabathi liphela ngenxa yokuba amalungu aluhlaza (ii-resistor, ii-diode, iinzwa ezingenangubo) axabisa kancinci kakhulu kuneemodyuli ze-breakout. Nangona kunjalo, eyona ndleko yazo yokwenyani eklasini ihlawulwa ngokutshintshwa rhoqo kwee-jumper ezonakeleyo kunye nokudinwa kukatitshala.
KwiBanga lesi-7, iibhodi ze-breadboard zilungele kuphela iiyunithi ezimfutshane, ezizodwa ze-elektroniki apho indlela yangaphakathi yombane ye-breadboard (ulwakhiwo lweziqwenga zentsimbi) iyeyona nto ifundiswayo esifundweni. Ukusebenzisa iibhodi ze-breadboard njengomqolo wocingo kwiirobhothi ezihambayo okanye iikiti zeerobhothiki ezineenzwa ezininzi phantse rhoqo kubangela uxhulumaniso oluxegayo ngexesha lokuhamba.
Ukhetho 2: Ii-Screw Terminal
Ii-screw terminal zibonelela ngoxhulumaniso oluqine ngokukodwa olumelana lula nokungcangcazela okubangelwa ziimoto ze-DC zohlobo lwe-gear kunye nokuhamba kwee-chassis ezinzima. Xa sele ziqiniswe kakuhle, ucingo alunakutsaleka luphume ngexesha lokuvavanya.
Owona mqobo wazo omkhulu eklasini kukucotha kokuzicwangcisa. Ukunika izikrufdrayiva ezincinci kubantwana abangamashumi amane abaneminyaka elishumi elinesibini kubangela ukuguga kwee-screw head, ukulahleka kwezikrufu, kunye nokwaphuka kweengcingo zangaphakathi ngenxa yokuqiniswa kakhulu. Ii-screw terminal zilukhetho olugqwesileyo lobunjineli kwiziseko eziqulunqwe ngutitshala ezihlala ixesha elide—ezifana nokukhusela iipakethi zebhetri ze-12V kunye neentambo zeemoto kwiibhodi eziqhubayo—kodwa zicotha kakhulu kumalungu ekufuneka abafundi bawatshintshe rhoqo ngexesha lesifundo esinye.
Ukhetho 3: IiKhebula ze-Modular eziKhiyelwayo (Grove, RJ, okanye i-JST eKhiyelwayo)
Iinkqubo ze-modular zibeka iinzwa kunye nezinto ezisebenzisayo (actuators) kwiibhodi ezincinci ze-breakout ezidityaniswe ngeekhebula ezikhethekileyo ezinamaphini ama-3 okanye ama-4. Isihlanganisi singangena ngandlela-nye kuphela, nto leyo ekhusela iintambo zombane ekutshintsheni kwecala, kwaye sicofa siqine endaweni yaso.
Ukugxekwa okuqhelekileyo kweenkqubo ze-modular kukuba zenza "imfihlo ye-black-box"—abafundi abazifakeli i-pull-up resistor okanye i-capacitor ngokwabo. KwiBanga lesi-7, oku kuluncedo kakhulu endaweni yokuba kube yintsilelo. Ezona ziphumo ziphambili zokufunda kwikharityhulam ye-CAPS yeSigaba esiPhezulu sokuqala kukucinga ngokwe-algorithm, ukutolika idatha yeenzwa, iimeko (conditionals), kunye nokudityaniswa koomatshini. Iikhebula ezikhiyelwayo ziphelisa ingxolo yokulungisa iingcingo ezibonakalayo ukuze abafundi bakwazi ukugxila ngokupheleleyo kwikhowudi nakulwakhiwo lwenkqubo.
Ulwakhiwo oluCetyiswayo lweGumbi lokuFundela leBanga lesi-7
Owona miselo weklasi owomeleleyo yimodeli edibeneyo eyahlula ucingo olusisiseko kulingo lweemodyuli zeenzwa:
- Isiseko esiQinisekisiweyo esinee-Screw Terminal: Izinto ezisebenzisa umbane omkhulu nezidibana nokungcangcazela okukhulu (iingcingo zebhetri, iimoto ze-DC ze-chassis) kufuneka zifakelwe kube kanye kwii-screw terminal okanye kwii-header eziqiniswe ngomthengisi ngutitshala okanye igcisa lelebhu.
- Iinzwa eziTshintshwayo ngeekhebula ze-Modular: Iinzwa ze-ultrasonic, ezilandela umgca, ii-potentiometer, kunye nezibonisi kufuneka zixhanyulwe ngeekhebula ezikhiyelwayo ezinamaphini ama-4. Oku kuvumela abafundi ukuba batshintshe irobhothi ukusuka ekulandeleni umgca iye ekuphepheni imiqobo phantsi kwemizuzu emibini ngaphandle kweempazamo zocingo.
- Ukutshintshela kwi-Breadboard kwiBanga le-9: Ngenisa iintambo ze-jumper ezizimeleyo kunye neebhodi ze-breadboard kuphela emva kokuba abafundi beziqonda iindidi zemiqondiso (idijithali xa ithelekiswa ne-analogue, i-I2C, i-SPI) kwaye baphuhlise nobuchule bezandla bokufaka iiphini ngaphandle kokugobisa iingcingo.
Ukuba ucwangcisa ukuthengwa kwempahla yelebhu yesikolo kwaye kufuneka ulungelelanise uhlahlo lwabiwo-mali lokutshintsha izixhobo ngokuchasene nobude bexesha lezifundo ezisebenzayo, jonga iinketho zethu zokufumana izixhobo zelebhu okanye ukhangele iikiti ze-hardware ezivavanywe eklasini kwi-venkile yakwa-Sheen Robotics.
