hi everyone!!!
I have an assignment that requires us to design a DC regulated power supply(AC to DC) that is able to display the digit 0 to 7 in an LED array for indication purpose....the following are the specifications:
1) 3 control switches for digit display
2) Input is 240V from TNB
3)The current in each LED is 10mA~20mA
4)Only discrete component allowed
5)Power indicator and necessary safety feature required.
I am required to design the LED array by myself that can display digits....any help would be wonderful....thank you so much....my deadline is coming up soon...
