About this project
To read analog input voltages in the range say 0 to 5V ADC0804 is commonly preferred for low voltage applications. But guess what?
To capture analog inputs with higher precision, i.e. above 5 volts, it is critical to measure with ADC0804. Moreover the cost is high. Instead of buying ADC0804, you can choose Arduino Nano to build DIY digital voltmeter.
Here’s why?Well, as a matter of fact, digital voltmeters make use of ADC to read input voltages given from the external world.
- Arduino Nano is a low-cost, microcontroller-based development board.
- It has a built-in analog sensor with eight analog input pins so that you can connect up to seven analog sensors.
- The measuring DC voltage varies from 0V to 55V.
In this project you can measure typically up to 48V. It is recommended to use Arduino digital voltmeter as “0-48V DVM”.
The only real question to ask yourself is this: What are the advantages of “Arduino Nano DVM”?
Advantages- Low cost DVM to calculate input voltages.
- Better accuracy.
- Easy to build without hassle.
You will be glad to know how to build Digital Voltmeters with Arduino Nano. Check this out to know more about this Arduino project.
