All that remains is the grid. When held at 0 V, it turns off all the segments, regardless of the potentials driving them.

Following our coverage of a 4.3-inch ESP32-S31 display development board, a Facebook reader pointed out the GUITION JC3636F118C-I-YR1 rotary encoder with ...

Seeed Studio has introduced the XIAO IPS touch display series, a family of six compact development boards built around the ...

So I started looking for a way to see the server without opening anything. Luckily for me, I have been into microcontrollers ...

Slow refresh, ghosting and low-contrast — wait, are we talking about passive matrix LCDs, or e-paper displays? That might be ...

Last time, I confirmed that each component was working properly with a simple program. This time, I will actually try watering. It took quite a long time due to program improvements and video editing.

I wanted a clock that, annoyingly, didn’t seem to exist. Since childhood, my bedside clocks have been a series of red, seven-segment LED clock-radio specials from Walmart or Target. They are ...

Connect LEDs to Arduino digital pins Use resistors to protect LEDs Control LED states with digitalWrite() Create timing sequences with delay() Build a repeating control loop in Arduino code These same ...

This project demonstrates how to build a compact portable digital voice recorder using an ESP32-S2-based IndusBoard Coin, an INMP441 I2S MEMS microphone, an OLED display, and a microSD card. Unlike ...

Unlike an Arduino board that requires external components to be functional, a Raspberry Pi is a powerhouse by itself right out of the box. It is, after all, a computer. This means that by simply ...

Creative clocks are a dime a dozen, even clocks that use binary have been created in nearly every format. [typo] promises a clever adaptation to the binary format, and it promises a more usable ...
