Vres = Vcc*(R2/(R1+R2))
Vres = Resultierende SpannungResulting Voltage
Vcc = Anliegende Spannung Input voltage (5V)
R1 = Erster Widerstand (Fotoresistor1st resistor (Photoresistor in our case)
R2 = Zweiter Widerstand 2nd resistor (Festwiderstand)Für unseren Fotoresistor ergibt sich also folgende Schaltung…Fixed resstiro)
For our photoresistor there is the following circuit:
Example-Code
For the code, let's output the values read from Arduino via the Serial Monitor (see: Serial).
