Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a ...

We’ve taken the versatile processor behind the Arduino Leonardo, and combined it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. Then, we ...

Now the goal is the same but he has an even more surprising plan, throw the ADC out entirely and sample an analog thermistor using digital IO.
