The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has him ...

With supply chains breaking due to the pandemic, some resources are becoming hard to procure. There are cases when someone’s profession or life, depends on these resources. Being a technical author ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

Most microcontrollers have a pulse-width modulator (PWM) output that can effectively drive variable output loads such as proportional solenoid valves, motors, or light dimmers. You control these loads ...
