analogread arduino
Reads the value from the specified analog pin. The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer valu,跳到 Read Analog Voltage - This example shows you how to read an analog input on analog pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor of the Arduino Software (IDE). ,Reads the value from the specified analog pin. The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer valu,Reads the value from the specified analog pin. The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer valu,Analog Input. In this example we use a variable resistor (a potentiometer or a photoresistor), we read its value using one analog input of an Arduino or Genuino board and we change the blink rate of the built-in LED accordingly. The resistor's analog ,Writes an analog value (PWM wave) to a pin. Can be used to light a LED at varying brightnesses or drive a motor at various speeds. After a call to analogWrite() , the pin will generate a steady square wave of the specified duty cycle until the next call t, Analog Read Serial. This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage thr,bits : determines the resolution (in bits) of the value returned by the analogRead() function. You can set this between 1 and 32. You can set resolutions higher than 12 but values returned by analogRead() will suffer approximation. See the note below for , Arduino Basic (6) – AnalogRead 類比輸入. 前面幾節講的都是數位的處理，也就是只有0 和1 兩種訊號，但我們的世界並不是只有0 和1 兩種訊號而已，我們還有更複雜的類比訊號。 諸如電壓、聲音、光亮、溫度等等的，都無法單純的由0 和1 構成。 那當我們需要處理這些訊號的時候該怎麼辦呢？ 這時候就是ADC ..., 在loop()裡，以analogRead()讀取類比腳位的值，Arduino裡有類比數位轉換器（analog-to-digital converter），會將這個腳位的電壓轉為0~1023範圍裡的數值。取得後放在potValue，然後，我們利用函式map()將這個數值對應到1~50的區間內。隨著可變電阻的轉動而改變，進而控制呼吸燈的循環時間。 參考資料：.
