An Arduino UNO microcontroller based digital voltmeter has been designed and developed with liquid crystal display and voltage range indicator. A regulated low voltage power supply circuit (5 volt) has been developed to power up Arduino microcontroller. Arduino senses the input voltage, converts the ...

Using double adjustment potentiometer to ensure good contact, effectively protect the load. Notice: The minimum differential between input and output is 3V the input must be higher than the output voltage above 3V to be regulated. Buck, not boost, when input 5V output 1.25-2V, not 6V. ...
ZMPT101B & Arduino AC Voltmeter Blueprints I don’t see people playing with ZMPT101B much on the internet. Luckily, I got better results thru the “serial monitor” code adapted from herehttps://solarduino.com/how-to-measure-ac-voltage-with-arduino/(my code is just something quick and di...
Here is a mains-operated doorbell that produces parrot-like sweet voice without requiring any musical IC. The circuit is cheap and easy to construct. The AC mains is fed to the circuit without using any step-down transformer. The complete circuit is shown in Fig. 1. The main components of...
