Hi all,

This is my first post in this forum.

So basically i want to use an 8051 microcontroller where I will have two input buttons (up and down). Every time the up button is pressed, the output of this 'unknown component' will increase by 10mV. When the down button is pressed, the output will decrease by 10mV. (please see attached photo)

Can someone please help me in what component to use that will increase and decrease the output by 10mV every time the input buttons (up and down) are pressed ??

all kind of help will be appreciated :)

Thank you in advance

If you don't have it, get the data sheet on the 8051.
We can help, but you'd help yourself by laying the groundwork for yourself.

Since the 8051 doesn't have analog outputs you'll need what is called a D/A Converter (or DAC, Digital to Analog Converter).
