Maybe you’ve used an HD4480-based LCD before (pictured) and you know that it requires a potentiometer for adjusting contrast. Is there a way to remove this potentiometer completely?
Read More »All About Microcontroller Power
I got plenty of questions regarding microcontroller power outputs and requirements especially for popular ones like PIC or the Arduino. So I decided to answer all of them in this post. Technically, Raspberry Pi and BeagleBone Black are not microcontrollers (I like to call them microcomputers) but I decided to …
