circuit diagram
where would i find a circuit digram/component values for this so i can draw it using crocodile technology and then convert it using the pcb wizard software?
1 LM339
1 potentiometer
3 LDRs
6 resistors
3 LEDs
1 battery
1 switch
This is for a GCSE Technology and Design course in Northern Ireland exam board being CEA - I have covered night light circuits using ldrs and variable resistors with a tip 121 transistor
3 input ldr
the idea was to have a childs toy abit like a jigsaw -when you added the shapes,which would cover an ldr an led would then light up -image of type of toy can be seen here-http://www.elc.co.uk/category-536 -the blossom farm puzzle-thanks for helping-
