electronic combination lock

[magzie7]

for my A level electronics project, i am planning to build a electronic combination lock. i do not wish to use any type of PIC or microprocessor. i have looked at many examples from the internet and have found it all to be quite confusing. please help, any suggestions large or small would be greatly appreciated!!

Your requirement for not using a PIC or other controller is going to make it complicated and confusing, although I realise your requirement for it as part of your course!.

As already suggested, work on what you've already found until you understand it!.

He sead he wishes not to use an MCU not that he is not alowed to use one.

there are some types using only gates, for example NOT gates, or AND gates only. But the combination is not changable, if it is not required in yr project... or you have to change the place of buttons/cables to change the combination. The number of combinations is related with the number of gates. Relatively simple circuits.

You can find many if you google.

A parallelin serial out logic ckt can be the answer to your problem.
