Digital Electronics – The First Video YOU Should Watch
Join CaptiveAire for a professional development hour (PDH) about the basics of electronics and computer science. Several basic computing concepts are taught using various methodologies, from simple switches all the way to transistors and microcontrollers. These concepts include digital logic, binary arithmetic, memory and data storage, basic programming, analog to digital conversion, the use of protocols, and more. You’ll see many examples from the HVAC industry throughout.
To receive PDH certification for this video, please visit CaptiveAire.com/library and click Request Access under the Professional Development section. Fill out the form on the pop up that appears and click Send. CaptiveAire will then add you to a professional development portal where you can access a certificate to confirm your training.

That was a revelation to me re relays vs vac tubes.
I can explain the semiconductor part better ngl
19:44, small error. 12 represented by 1101 instead od 1100, which really made me question my binary math knowledge for a moment before i repized
This was so informative, in a way that explained this better than I’ve ever had it explained to me, even with my degree.
Thank you, I think so many little doors in my head just opened up to better understand.
I believe the resistor in the XOR gate at 19:06 is wired wrongly. The collector of the uppermost transistor shown connected to the 5V rail and resistor needs to be wired to the other end of the resistor and base of the ‘non-controlled transistor’. Otherwise when A AND B are activated there would effectively be a short circuit that would likely destroy the 2 leftmost transistors.
