Ulawulo lweeServomotors nge-PWM kunye neArduino-Ikkaro

Sele sibonakalisile kwibhlog Arduino (https://www.ikkaro.com/kit-inicio-arduino-super-starter-elegoo/) Kwaye enyanisweni zivela kwiiprojekthi ezininzi kubandakanya le (https://www.ikkaro.com/node/529)

Ngoku masiqhubeke phambili kancinci kwaye masenze moderate imiqondiso ngobubanzi ukubetha (PWM), oku kungasetyenziselwa umzekelo ukuphatha ii-servomotors ezinje ngale zichazwe apha (https://www.ikkaro.com/introduccion-al-aeromodelismo-electrico/) okanye i-rgb leds phakathi kwabanye. Kulabo abangaziyo ukuba yintoni i-PWM, yindlela yokumodareyitha eyenziwa kumqondiso kwaye isebenza "ukuhambisa ulwazi ngejelo lonxibelelwano okanye ukulawula ubungakanani bamandla athunyelwa kumthwalo" (Wikipedia)

Ii-servomotors zilawulwa ngeentambo ezi-3: enye yevolthi elungileyo, enye yomhlaba kunye nenye yesiginali yokulawula, emiselweyo kwi-PWM.

I-Arduino yenxalenye yayo ineziphumo ezi-6 zedijithali ezinokuthi zisebenze njengeziphumo ze-PWM (ezi zizikhonkwane: 11, 10, 9, 6, 5, 4) kunye nethala leencwadi elilungiselelwe ukuphatha iinkonzo. Ke siza kusebenzisa enye yezo mphumo ukwenza iimvavanyo zethu zokuqala zokulawula i-servo motor.

Ikhowudi yomzekelo wethala leencwadi le-Arduino linokusisebenzela, siqhagamshela i-voltage kwi-5v, umhlaba ukuya kwi-gnd kunye nophawu lokulawula lwe-servomotor (eyona izayo imodareyithwayo kwi-PWM) kwenye yezikhonkwane ze-arduino ezine-PWM, umzekelo kule khowudi ukuya kwipini yedijithali 9.
