    Led display Digital Voltmeter question

    OK thanks Now I've just finished making the pcb but i have to make the holes so i'll wait to monday to do it in the sochool (I go to an industrial school called PIO IX). Meanwhile I wonder If there's something else anyone should tell me about the pcb or the components.... Any more fixes apart...

    Led display Digital Voltmeter question

    OK Emiliano.....voy a seguir tu consejo (I WILL TAKE YOUR ADVISE)....... Now I'm doing the PCB but i have a questio: WHICH R1 SHOULD I PUT?? 180K or 100K??? The kit says that R1 is 100K but in the datasheet 180K What should i do? Thanks!!......(AGUANTE EL PIO IX)

    Led display Digital Voltmeter question

    Hi.... I pieced the voltmeter on a protoboard (bradboard) and it doesn't works well The measure it's very unstable.....I think that maybe it's my fault but it's very improbable because i used the fixed schematic and i compared it with the datasheet and it was ok!! Also it's doesn´t...

    Led display Digital Voltmeter question

    Sorry....i forgot to say something........in the pcb all the pin 5 of the MAN6760 (which is the pin of the dot in the display) are send to ground!!!.........IN THAT CORRECT!!!??? (i don't think so)... OK that's all.....thanks again........

    Led display Digital Voltmeter question

    Hi......I'm here again........with more doubts :-\ First of all i would very happy if another person corrovorates if this circuit displays two decimal when measurin from 0 to 20. And my other question is: Which R1 should i use!!!?? 180K or 100K (in the datasheet and in the eagle circuit says...

    Led display Digital Voltmeter question

    Hello... Before starting to do this circuit There´s something i must know!! I want to place this circuit in a power suply which goes from 0 to 20V ......and i was wondering if it this circuit displays the voltage with two decimals or only one.....(when you are using the R3 for measure...
