So i'm currently trying to take parts out of a Bluetooth speaker's circuit-board and find the Bluetooth module for a DIY project.
I looked at the board and some ICs and tried looking them up to no avail.
So How Do you read an IC or any other components on the board Or even find a schismatic...
I would like to make a digital clock with HOURS and MINS using 74LS192 IC. Below attached is my schematic diagram for the connection of the circuit. However, the MINS counter keeps counting from 00-59 and resets and does not increase the HOURS counter after each 60mins.
I'm working on a project in NI Multisim i simply cannot find two Balance ICs: HY2210 and HY2213 or their replacements or some circuit or SPICE models.
I've searched ewerywhere I could think of and no sings of such.
Please, help me.
