This is the easiest and fastest way to get the LED Clock up and running. I mostly use "ESP-WROOM-32 Devkit" as microcontroller for my projects (I may will move to ESP32-C5 in the future as this is the ...
Split-flap displays are a great, low-power way to display text to a wide audience. Compared to other display technologies ...
I programmed a $7 ESP32-S3 board to block all computer's web ads - and it took just minutes ...
These new AI-focused SBCs pair multicore processors with integrated NPUs for edge computing, robotics, and embedded ...
Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...
Espressif’s ESP32 series is the go-to choice for many people looking to take on microcontroller-powered projects. Not only are they cheap and versatile, but they’re also available in a variety of ...
Stepper motors use a cogged wheel and electromagnets to rotate the wheel one ‘step’ at a time. Each HIGH pulse sent to the A4988 stepper driver energises the coil, attracting the teeth closest to the ...
In this article, we’ll walk through how to convert digital circuit files originally created in offline Multisim formats such as MS13 and MS14, and run them directly inside TINACloud. The same ...
Timing of laser activation was recorded using a microcontroller board (Arduino UNO Rev3) connected to the pupil tracking computer. The pattern of light activation was the same as for optogenetic ...
