Programmable 8-character LCD module and digital voltmeter

Wednesday, July 22nd, 2015

A programmable 8-character LCD module and digital voltmeter project from Tuxgraphics: Our 3 digit LED digital voltmeter module has been quite successful over the years. This new LCD module is basically an advanced version with a lot more capabilities. You can power it with the same voltage source that your...

Voltmeter clock project

Friday, August 8th, 2014

Here's a voltmeter clock project based on a multimeter clock design by Alan Parekh: I have used three voltmeters and mounted them on a wooden plinth with a clear Perspex cover to give the clock an industrial look. I have modified Alan’s code to run on PICBasic Pro version 3....

I2C LED Display from Hacked Voltmeter

Monday, August 26th, 2013

Tom writes: I turned up this cool project write up that reprogrammed a cheap LED voltmeter for use as a general purpose 7 segment display with I2C communication. These voltmeters cost about $3 instead of $10 for an equivalent LED display backpack from Adafruit. NB the author used a Bus...

Digital clock from an old nixie tube multimeter

Wednesday, December 7th, 2011

James built a digital clock that displays the hours and minutes on an old Nixie tube multimeter. The multimeter functions as a voltmeter that is reading the output of an Arduino generated voltage. There are still some noise issues to clear up, but all in all it's a cool looking...

Voltage monitor for car’s battery and its charging system

Tuesday, October 11th, 2011

Raj designed a car battery volt-meter. The core of the project is a PIC16F1827 which uses its internal fixed voltage reference FVR and ADC to precisely measure the battery voltage. Measured voltage is displayed on a 4 digit 7 segment display. His circuit is connected to the car's battery through a standard...
