DIY Analog VU Meter and Clock


 This is a neat project. The DIY Analog VU Meter and Clock can move to the music when in VU mode and also act as an analog clock to let you keep track of time.

“I made an old style analog VU meter and Clock using 2 analog panel meters, an Arduino, a real time clock, and other simple components. How it works: The unit plugs into a standard 3.5mm speaker jack. The Arduino reads the sound levels and converts it into electric pulses (PWM) to control the analog meters. When no sound is detected, the unit automatically changes to Clock mode and displays the time which is read from the real time clock circuit.”

    Wicked cool!

    Cool idea indeed! I am wondering though how linear is the position of the needle when it’s responding to PWM given that it’s a DC voltmeter.
