Hauv tsab xov xwm dhau los, kuv tau qhia koj yuav ua li cas nyeem ADC tus nqi los ntawm Potensometer siv Arduino.

Thiab lub sijhawm no kuv yuav ua kom zoo dua ntawm kev nyeem los ntawm ADC tus nqi.

Qhov ntawd yog kho qhov ci ci ntawm LED.

Saib daim duab saum toj no rau phau ntawv qhia kev sib dhos, Arduino rau Component

A0 ==> 2. Potentiometer

GND ==> 1. Potentiometer & Katoda LED

+5V ==> 3. Potentiometer

D3 ==> Resistor series nrog leds

Kauj ruam 3: Programming

Luam cov cai hauv qab no rau koj daim duab:

int LED = 3;

void teeb tsa () {

pinMode (LED, NTAWV); Serial.begin (9600); }

void voj () {

int sensorValue = analogRead (A0)/4;

analogWrite (LED, sensorValue); }

kos duab hauv daim ntawv ntawm thawj daim ntawv, tuaj yeem rub tawm ntawm no:

Kauj Ruam 4: Qhov tshwm sim

Saib cov vis dis aus saum toj no kom pom cov txiaj ntsig.

Thaum lub potentiometer tig mus rau sab xis, cov coj yuav ci dua.

Thaum lub potentiometer tig mus rau sab laug, LED yuav dimmer.
