hello all,
I want to design a digital power supply....(I dont know whether the name suits my circuit)
Here is my idea
A power supply which can give a wide range of voltage 0-30v.
The required output voltage can be selected with a button switch.
If the button is keep on pressed, the output voltage should go 1v 2v 3v 4v ....
if the button is pressed once, the voltage should go from 0v to 1v. again if pressed 1v to 2v. so, i need two modes. continuous pressing and single step pressing.
one more button switch required to do the reverse operation.
what my idea is....
a button switch - 555(mono) - 4017(10 outputs) - 4066 (analog switches which connects different resistors to adj of LM317)
Is it clear? or shall i put an attachment. it takes some time to draw in paint.
