I am doing electronics at a GCSE level and am doing course work for it. I am creating my final circuit for a lock and alarm mechanism, I have used PTM’s and thyristors to create ‘code’ so when the PTM’s are pushed in the right order it activates a solenoid. I know I do not have the most efficient resistor values but I will fix that some other time. My problem is that I want to link that circuit to a decade counter, so every time I get the code wrong when I hit the enter button it activates the decade counter and actives the LED. But every time I try this the NOT gate and Decade counter blows up as they can only take 1 volt according to yenka. My teacher says the components should be to handle more volts but I’m not sure if it will work. I have attached the circuit.
Thankyou

No circuit?

 

Without simulation file or diagram how we can help ??

 

...But every time I try this the NOT gate and Decade counter blows up as they can only take 1 volt according to yenka...

Are you absolutely required to use yenka? Last time I used it it was a really crappy "simulator".
