Happy New Year to everybody here. I have a problem: I wanna use one single LCD (16*1) for 2 diferent proyects (frecuency meter and LCmeter). I will use one and later the other. In other words, i will not use the both circuits at the same time, one first and the other later :)

hi,
How are you driving the LCD.? PIC etc?
If you are writing your MCU programs, you could program the MCU to be either a Fmeter or LCmeter..

It would be useful if you could post a simple block diagram on how the two meters and the LCD are required to be connected..:)

I'm drivind the LCD with a pic,but dont do the code :(
Here are the schematics of both meter

hi,
Only one, the LC, schematic is shown..:confused:
 
The super probe could use a LCD display.

The unit is designed to have as many functions possible using as few parts as possible. It works surprisingly well. A little TLC and a handful of parts might result in an improved tool. The voltmeter function is limited to +5. A nice autorange voltmeter without that limitation would be nice.

Ones a frequency counter the other is an LC meter. Which one do you want to build?

You can buy a Meter with a frequency counter & LC Meter for about $50US

If you look through their product line you'll find one with the works. I don't recall the model number but the manual range one is $49 CDn on College st in Toronto.
