VU-meter circuit built on a breadboard using transistors, diodes, resistors, and LEDs @ Build Electronic Circuits: It’s basically a simple display for showing a value. It’s originally for showing signal level in audio circuits, but there’s no reason you can’t use it to show temperature, rain intensity, light level, or whatever other value you are […]

LED VU Meter with LM3916
xristost has written an article about his latest project LED VU meter with LM3916: This was finished months ago and just now I had time to finish the article. LM3916 is a dedicated IC for VU LED meter. Unlike LM3915 which have 3dB step between voltage levels, the LM3916 have nonlinear steps: -20, -10, -7, -5, -3, -1, 0, […]
MSP430 based 32 LED driver
Parker designed a MSP430 based 32 LED driver. His intends to use it as a VU meter, by reading a ADC line with the uC and turning LEDs on and of depending on the calculated VU level. Finished the VU. Changed the name to a 32 LED Driver as that is what it really is. […]
