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. <h3 >Here’s why?</h3>Well, as a matter of fact, digital voltmeters make use of ADC to read input voltages given from the external world.<ul ><li >Arduino Nano is a low-cost, microcontroller-based development board.</li></ul><ul ><li >It has a built-in analog sensor with eight analog input pins so that you can connect up to seven analog sensors.</li></ul><ul ><li >The measuring DC voltage varies from 0V to 55V.</li></ul>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”?<h3 >Advantages</h3><ul ><li >Low cost DVM to calculate input voltages.</li></ul><ul ><li >Better accuracy.</li></ul><ul ><li >Easy to build without hassle.</li></ul>You will be glad to know how to build Digital Voltmeters with Arduino Nano.
