epodandy Posted September 1, 2004 Report Share Posted September 1, 2004 Would appreciate if some one can show me how to build a small cmos or equal selector switch using one push to select 6 different colour LEDs.Input Voltage is 3VDC.Thanks Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 1, 2004 Report Share Posted September 1, 2004 Hi Epodandy,Welcome to our forum.You could use a CD4017 or CD74HC4017 (higher output current)stepper to select the LEDs, and a monostable circuit to de-bounce the button. But it will need a step-up voltage converter to light 3.5V or more blue, white or purple LEDs from only 3VDC.Yes, purple. I was sent some substitutes for the blue LEDs that I ordered, and they were the new purple ones by mistake! Quote Link to comment Share on other sites More sharing options...
