  • Control an LM317T with a PWM signal
  • Hi please use LM358 or any other single supply opamp. I have made this and its working properly. LM741 was used as a reference to an opamp with null offset adjustment. I can see the info in article is misleading. Sorry for any inconvenience that might have caused

  • Read 10 or more switches using only two I/O pins of a microcontroller
  • Actually if you read carefully you will see that I have presented methods to both interrupt based and polling options to read the switches. Regarding low power systems, it depends on how "low" is the low power is defined. we always have to sacrifice one thing for other right? :)
