Arduino ADC 讀取函式

Arduino ADC 讀取函式 int analog. Pin = A 0; int val = 0; void setup() { Serial. begin(9600); } void loop() { val = analog. Read(analog. Pin); Serial. println(val); delay(1000); }

LS-Sensor電路圖

Ex 5_0: LS光照度值顯示OLED //-------Declare-OLED-------------#include <OLED. h> OLED my. OLED; //-------Declare-Light Sensor ---------#define LS_PIN A 0 void setup() { //===== Setup LS ======= pin. Mode(LS_PIN, INPUT); // ====== Setup OLED ======= my. OLED. begin(FONT_8 x 16); my. OLED. clear. Screen(); my. OLED. println("ex 5 -0_LS"); my. OLED. println("XXXXXX"); }

Ex 5_0: LS光照度值顯示OLED-2 void loop() { // read the value from the sensor: int LSVal = analog. Read(LS_PIN); my. OLED. set. Posi(4, 0); my. OLED. print("LS_Val: "); my. OLED. println(LSVal); delay(500); }

Ex 5_1: 光照度開關 (光照度� 控制LED ON/OF) 複製Ex 5_0_LS_OLED 到Ex 5 -1_LS_OLED_LED加 入下列宣告設定資料 //-------Declare-LED 1 W-MD 1 ---------------#define LED 3 int Set_LS=200; void setup() { //======Setup-ED 1 WMD 1========= pin. Mode(LED, OUTPUT); my. OLED. println("Ex 51_LS_LED"); //修改標題 my. OLED. print("Set_LS: "); my. OLED. println(Set_LS); }

Ex 5_1: 光照度開關 光照度� 控制LED ON/OFF Loop加入下列Smart Processing void loop() { my. OLED. set. Posi(6, 0); //修改顯示位置 //=======Smart Processing======= if(LSVal > Set_LS) digital. Write(LED, HIGH); else digital. Write(LED, LOW); delay(500); }

Ex 5_2光照度PWM控制器()光照度調變PWM 複製Ex 5_1_LS_LED到Ex 5_2_LS_PWMLED 加入下列宣告設定資料 int Set. LSMax=400; int Set. LSMin=50; void setup() { //=====取代=========== my. OLED. print(“L 1: "); my. OLED. print(Set. LSMax); my. OLED. print(“L 2: "); my. OLED. println(Set. LSMin); } LED
