Potentiometers feem ntau yog siv tswj cov khoom siv hluav taws xob xws li ntim tswj ntawm cov khoom siv suab. Potentiometers ua los ntawm lub tshuab tuaj yeem siv los ua txoj haujlwm hloov pauv, piv txwv li, hauv lub joystick.
Dab tsi yog 3 siv rau potentiometers?
Cov piv txwv ntawm Potentiometers yog:
- Kev ntsuas txoj haujlwm ntawm kev ua si joystick.
- Tshwj xeeb cov cuab yeej siv suab siv lub ntim tswj.
Dab tsi yog potentiometer thiab nws siv?
Lub Potentiometer yogntsuas hluav taws xob siv los ntsuas EMF (electromotive force) ntawm ib lub xovtooj muab, sab hauv ntawm lub xovtooj. Thiab nws kuj yog siv los sib piv EMFs ntawm cov hlwb sib txawv. Nws kuj tseem siv tau los ua qhov sib txawv ntawm qhov sib txawv hauv feem ntau ntawm cov ntawv thov.
Dab tsi yog potentiometer siv los ntsuas?
A potentiometer yog ib qho cuab yeej uas siv rau kev ntsuas ntawm qhov sib txawv ntawm qhov kev paub txog kev tiv thaiv lossis nruab nrab ntawm ob lub davhlau ya nyob twg ntawm lub voj voog lossis network ntawm cov yam ntxwv paub. Lub potentiometer kuj tseem siv tau los sib piv cov emf ntawm ob lub hlwb.
Peb puas tuaj yeem siv potentiometer?
Potentiometers tuaj yeem siv ua qhov sib faib hluav taws xob. Txhawm rau siv lub potentiometer ua qhov sib faib hluav taws xob, tag nrho peb tus pins txuas nrog. Ib qho ntawm cov pins sab nraud txuas nrog GND, lwm qhov rau Vcc thiab nruab nrab tus pin yog qhov tso tawm hluav taws xob. Yeej, qhov hluav taws xob faib hluav taws xob yog siv los tig qhov hluav taws xob loj rau hauv ib qho me me.
