Anyone know an easy way to output a Vdc ramp up and hold or a ramp down and hold alternately when an input Voltage goes from low to high or high to low ??? changes state ??
Hope I have described that one correctly !!
Its for another project on this forum but thought I should keep it separate in case it could help anyone else looking for this solution!
Should I be using a 555 timer for this ? or just RC and transistor ? The ramp doesn't have to be perfect ramp ! only the duration ( speed of ramp ) is important.
Maybe this has been answered on the forum before but I couldn't find an example of a hold at the top or bottom of the ramp..
A very long time could work but infinite until Vdc input change would be cleaner design !
