A potentiometer (los yog "lub lauj kaub") yog ib qho khoom siv hluav taws xob siv los ntsuas angular txoj hauj lwm. Qhov sib txawv voltage no tuaj yeem ntsuas los ntawm qhov VEX microcontroller thiab yog ncaj qha proportional rau lub angular txoj hauj lwm ntawm lub ncej txuas mus rau qhov chaw ntawm lub potentiometer.

Cov lus nug tseem yog, VEX ncej encoder ua dab tsi?

Qhov Optical Ncej encoder yog siv los ntsuas ob qho tib si txheeb ze txoj hauj lwm ntawm thiab rotational nrug mus los ntawm a ncej . Nws ua haujlwm los ntawm kev ci ntsa iab mus rau ntawm ntug ntawm lub disk uas muaj qhov sib npaug sib npaug ntawm qhov ib ncig.

Tom qab ntawd, lo lus nug yog, puas yog lub potentiometer muaj tag nrho cov lus tsa suab? Cov Potentiometer yog siv los ntsuas qhov angular txoj hauj lwm ntawm lub qag lossis ncej dhau los ntawm nws qhov chaw. Lub arcs muab yooj rau orientation ntawm lub Potentiometer , tso cai tag nrho cov lus tsa suab kom siv tau yooj yim dua.

Qhov thib ob, Vex Line Tracker ua dab tsi?

Cov VEX Line Tracking Sensor tso cai rau tus neeg hlau qhia cov khoom lossis qhov chaw sib nrug raws li lawv qhov tsaus ntuj lossis lub teeb yog . Nws ci ib lub teeb ntawm lub teeb infrared tawm mus rau qhov khoom, thiab ntsuas seb lub teeb puas rov qab los. Cov Kab khiav Sensor yog ib qho analog sensor, thiab nws rov qab muaj nuj nqis nyob rau hauv thaj tsam ntawm 0 txog 4095.

Dab tsi yog tus nqi siab tshaj qhov potentiometer yuav nyeem?

Nws yog tus nqi max yog 500 Ω thiab lub zog ntsuas yog 0.2 W, yog li max Tam sim no yog 20 mA.
