KiCad 8 just dropped, and here are Bald Engineer’s eight must-try features! The February 2024 release brings a whole host of new stuff to the Schematic editor. However, the PCB editor, CLI, and Simulation tools also received attention. (There are something like 900 closed issues for the 8.0.0 Milestone!) Which of these is your favorite?
<br /> This Addohms Brushed DC Motor Tutorial goes into the third dimension! Using a variety of 3D models, we show you what makes a brushed DC motor, a brushed DC motor. Then, like usual, we break two simple ways to control them with a microcontroller like the Arduino. You can use a single BJT Transistor (remember those from #10?), build your own H-Bridge, or use a popular H-Bridge chip. Brushed DC Motors Show Notes This…
Using Push-buttons with a microcontroller like an Arduino or Launchpad is made much easier with “Pull-Up Resistors.” See how they work and why you need them in this video tutorial.
https://youtu.be/EQtwsWJuUPs Understanding voltage dividers means understanding Ohm’s Law. A common use for a voltage divider in most projects is to monitor a battery. Say you are powering your circuit with a 9V or 12V battery. Microcontroller boards don’t do well with those voltages. In a future video, we’ll come back and look at more circuits that can use voltage dividers. Episode Notes Correction: There is a mistake around 3:00. I say “91 millivolts” and I should…
