Get to Know Your ADC with a DIY Temperature Probe (9x34)

Udgivelsesdato: Sep 20, 2019

As makers and engineers, we frequently incorporate microcontrollers, single board computers, and external sensors into our projects. This often requires that we interface our digital circuitry to the analog world. But do you really know what’s going on under the hood of that ADC you’re using? In this video, I cover the basics of using an ADC and focus on the successive approximation register ADC. With that knowledge, we put together a DIY temperature probe using an analog temperature sensor, custom enclosure and a novel method of turning the unit on and off.
