WebReading 4-20mA current loop sensors using Arduino is much easier than you might think. Follow this simple guide and we will show you a few tips to make it fast and easy. 4-20mA current loop is most common and widely used communication method … WebFeb 8, 2014 · If you need to read in a voltage on an Arduino digital or analog input pin, ensure it is between 0 and 5V. If it is outside these limits, you can bring down the voltage using a voltage divider. This scales the input voltage to allow for analog or digital readings of voltages otherwise outside the allowed range. WebTo match the circuit diagram we will use A3: pinMode(A3, INPUT); and then do the analog to digital version by using the analogRead () command: int x = analogRead(A3); //Reads the analog value on pin A3 into x. The value that is returned and stored in x will be a value from 0 to 1023. The Arduino has a 10-bit ADC (2^10 = 1024). great mills pool hours
