  • where did you get the chip?

  • @MultiJohn12321 RS components

  • I am making this for a school project, in the schematic it calls for 2 resistors and 9vd/c how do you make it work with a coin battery and it looks like 4 resistors and a zener. is the schematic a little different for the smd version?

  • @walsethk Please look at the website of josepino.com

  • would i be possible to do the same with an attiny85?

  • @liutas1245 You need a programmer, the hex file is available in the page listed above

  • can i also made this with a 555 ic ?

    thanks for answer

  • If it needs so what programmer did you used ?

  • I want to try this schematic and i have a question . Do I need to program this MIC ????

  • Can anyone please help what is the components I need? please write a list THANKS!

  • @marc1979Guitare I believe he hasn't used a zener diode because the battery is only a 3V battery and the PIC12 is rated for 5.5V. If you look at the schematic, he actually stated he was using a 9-18V battery which he didn't opt for and therefore didn't need the zener diode.

    The zener diode in the application he's stated in the schematic is actually wrong. The battery wouldn't last long with all of the wasted current and maybe even enough to burn it out.

  • You didn't put zener diode on it??

    thanks !:)

  • me gusto mucho tu tutorial amigo
