AVR vs PIC, Round 223: Fight!

Get ready to rumble! made the exact same Hello-World-esque project with two microcontrollers (that are now technically produced by the same firm!) to see how the experience went. 285 more words


ATtiny85: Debounce Your Pushbuttons!

The image above exemplifies why you need to debounce your pushbuttons.

When people push a button, they expect one reaction per push. Due to the springy nature that pushes back at you when pressing them, buttons tend to bounce around when pressed and released, which… 2,287 more words


ATtiny85: Introduction to Pin Change and Timer Interrupts

Often when a microcontroller is being used, we want it to know when certain things occur, and then have something happen in response. A simple example is to have a pushbutton determine when an LED turns on. 1,954 more words


ATtiny85: Blinking Without Clock Cycles

In the previous post we learned how to blink an LED with an ATtiny85 by using a _delay_ms() function to halt the program execution after turning on and off the LED. 1,267 more words
