OK Brian,I see what you're saying. (I was going ass about face)!
I going to try using a HCF4532 encoder to a 74C138 decoder for dedicated switching outputs to the LED's.. I'm a little in the dark about the timing of 2 second output to each of the LED's though.
Best regards.
Hi Brian
Preferably I would like LED 1 to time out after 2 seconds without LED 2 being able to light up even if it is activated accidently.If two buttons are mistakenly pressed,the first LED which was activated should light up and LED 2 should not light up until LED 1 has timed out after 2...
Hi Brian
Thanks for your reply. You are correct.This is exactly what I'm trying to achieve.Would I be using an astable or a monostable oscillator to clock the CD4017? Do you have a schematic for the complete circuit?
Best regards.
Could someone please help me with the following cct?
I am using a CD4017 clocked by a 555 one shot monostable oscillator. I need the 4017 to trigger 8 LED's independently by push buttons. Each LED,depending on which of the 8 push buttons are used,must have an ON time of approx 2 seconds.The...
