AC voltage measuring using arduino - Arduino Forum - Index
Differential voltage measurement with Arduino UNO. Ask Question 1. 1. V = IR = 0. 004 * 220 = 0. 88V. So with a 220Ω resistor you would get a voltage reading of between 0. 88 and 4. 4V on the Arduino. (Note: the datasheet recommended 100Ω would be more suitable for a 3. 3V Arduino - …
How can I measure AC voltage in the range 0-250 VA - Arduino
Your method and algorithm to use zmpt101b module for AC voltage measurement is superb. But I was wondering if one can use a diode bridge rectifier along with the capacitive/resistive filter on the output pin of the module and then convert it to constant DC to be read on Arduino ADC Pin. Kindly comment. regards, Noman. Reply Delete

It's easy to make a simple digital voltmeter using an Arduino and 16x2 liquid crystal display Make a Digital Voltmeter Using an Arduino. 10k, 220, 330). Thanks! Reply. RK37 2018-01-10. You can use different resistor values, as long as the ratio between the two resistors is the same, because the goal is to create a 10:1 divider.
