When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you might ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, vacuum tubes, and transistors being some well-known examples. In a smaller ...

The exact time and date are obtained from the Network Time Protocol via Wi-Fi. For a smaller display, about 0.8-inch schematic diagram is very simple. Problems are with large segments, containing more ...

This project is also available at Max Imagination’s Workshop. Welcome, fellow makers! Today, we're diving into the world of productivity and time management with a hands-on project – the Arduino ...

所有微控制器都有特定数量的 IO 引脚，但在某些应用中，例如在 7 段显示器中，我们需要的 GPIO 引脚数量将超过我们的控制器所能提供的数量。对于这种需要多个输出引脚但微控制器的输出引脚数量有限的情况，74HC595 移位寄存器将是一个完美的选择。74HC595是以 ...

Nowadays, visual indication is a must-have feature for any electronic device, which will make user interaction much easier. There are multiple ways to implement the visual indication, from simple ...

Developed originally to easily display numeric and text data on the cheap and popular 7-segment led displays or "tubes", from 1 to 8 digits, like the "4-Bits LED Digital Tube Module" (and for all the ...

If you want read-only memory today, you might be tempted to use flash memory or, if you want old-school, maybe an EPROM. But there was a time when that wasn’t feasible. [Igor Brichkov] shows us how to ...
