Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...

The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

This chapter, like its predecessor, focuses both in hardware and software related to PIC microcontrollers. In the second part, we made an attempt to blink one LED through a PIC microcontroller ...

Just got your hands on an ESP32? Don’t dive into a complex first build; start slow with something simple. These projects will introduce you to basics like flashing your microcontroller, adding ...
