In the first part of our look at measuring voltage and current with microcontrollers, we will see how to measure DC voltage and current using an Arduino. In part two we will do the same thing with AC, but today our focus is on Direct Current. Introduction There are many reasons why you...
However, With this method, you can only measure voltages from 0 to 16.5V DC.Measuring Voltage with a 3.3V Reference To use this method, you need to set up both the hardware and the code. For the hardware, connect the AREF pin of the Arduino to 3.3V as shown in the diagram below. ...
A voltage source input that you would like to measure with the Arduino analog to digital converter ranges from0to25V.Since the Arduino ADC can only read voltages between0V and5V,you use the voltage divider below to drop the source...
In the attachments above, we can see for different ranges of voltage that no matter what voltage we have, the output current is always 0[A]. Dividing it with 0[A] output current will lead to Rinput = (Voltage(in)[V])/(Current (in)[A])=(Voltage(in)[V})/(0[A]) = ∞ Meaning...
Operating Voltage = 2.4V to 3.6V Light Intensity Range = 1 to 65535 LUX (small variation of +/- 20%) It consumes 0.12mA current and in power-down mode, this value is further reduced to 0.01µA. Communication Interface: I2C
digitalWrite(3, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(3, LOW); } Working of Arduino Sound Level Meter: Once you are ready with the code and hardware, just upload the code and open your serial monitor to look at the...
