How to measure voltage and current measurement using

The Arduino generates an accurate 1 second time base for the counter by cascading timer0 and timer2. The link between digital inputs 3 and 4 connects the output of timer2, 250 Hz, to input of timer0. The software waits for the output of timer0 to go positive to start the count of frequency input to timer1.

Make a Digital Voltmeter Using an Arduino; Make a Digital Voltmeter Using an Arduino. June 04, If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input. To display the measured voltage, we will use a liquid crystal display (LCD) that has two lines of 16 characters.

The Arduino then sends to the Bluetooth 5 bytes of data in serial RS232 protocol. The Bluetooth module HC-05 can be paired with the phone using the code 1234. The frequency input is TTL signal levels, for low signal a video amp has to be added. The specs recommend input up to 6 MHz, I tested it at 2 MHz. The voltage input is 0-5VDC.
