AK-95 D.I.Y 4 Bit Digital Clock Kit
This kit is a simple soldering practice board, the goal is to build a digital clock! Using the Abra Kits guideline we have streamlined the manual to offer a schematic diagram, a parts list and basic soldering guide. This makes our manual ideal for classrooms who want no non-sense straight forward guide. This clock has two alarms and on digital clock, when powered off the settings will be reset. If you would like to save the time when power is cutoff please look into RTC circuitry. The Atmel microprocessor is pre-programmed, all you have to do is solder and supply 5v and ground to the terminal block. Please check the bottom side of the PCB board when looking for polarity of the terminal block!
