Hauv qhov kev qhia no peb yuav ua voltmeter Siv Arduino Uno. Qhov hom voltmeter no tuaj yeem siv los ntsuas qhov ntsuas hluav taws xob qis dua 0-5V.
Kauj Ruam 1: Cov Cheeb Tsam Yuav Tsum Tau:
1. Arduino Uno
2.voltage qhov chaw (tsawg dua 5V)
3. Wires
Kauj Ruam 2: Kev Sib Txuas:
1. Txuas tus Hlau ntawm Analog tus pin A0 hauv Arduino Uno.
2. Txuas tus Hlau ntawm lub dav hlau hauv av ntawm Arduino uno.
3. txuas cov khoom siv hluav taws xob nruab nrab ntawm cov xov tooj hluav taws xob sib txuas thiab cov xov hlau hauv av. Kev paub tseeb txog lub davhlau ya nyob twg qhov zoo ntawm qhov hluav taws xob qhov hluav taws xob yuav txuas ntawm Analog tus pin A0 xaim thiab qhov tsis zoo ntawm qhov hluav taws xob qhov hluav taws xob yuav txuas rau ntawm lub dav hlau hauv av ntawm Arduino Uno.
Ceeb Toom: Hom voltmeter no ua haujlwm ntawm 0-5V.
Kauj Ruam 3: Txoj Haujlwm:
rau txoj cai nyem rau: Voltmeter Code
Rub cov program hauv qab no hauv Arduino Uno:
ntab vol = 0; int tswv yim = 0;
void teeb tsa ()
{
pinMode (A0, INPUT);
Serial.begin (9600); // pib Serial Monitor
}
void lub voj ()
{
cov tswv yim = analogRead (A0); // analogRead muaj nuj nqi tau siv los txais cov ntaub ntawv analog
vol = (input*5.0)/1024.0; // formula siv rau kev nqis tes ua
Serial.print ("voltage yog:");
Serial.println (ntim);
}
Kauj Ruam 4: Tso Tawm:
Qhib Serial saib kom tau txais cov zis.
