#72534 - All done by program |
Hi~
I'm making a "quiz game controller" for my school. 6 players press their own buttons, and the first one will be indicated by some LED. I've finished the circuit board and find that the power supply is 19.xxV but the voltage I need is 12V. I can't use a 78L12 coz of the large current the LED takes. I'm currently using PWM to make the LED dimmer. The supply is 19V but the Vmax of LED is 12V. Is it a suitable solution in long run? Stanley |
