What is this repository for? Really tiny library to control multiplexed basic 7 segments displays. It can work with only a display but it's intended to use more than one and drive them multiplexed. If ...

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 ...

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 ...

A 7-segment display is commonly used in electronic display devices for decimal numbers from 0 to 9 and, in some cases, basic characters. The use of light-emitting diodes (LEDs) in seven-segment ...

There are two objects which must be created to use the library. The MAX72XX object defines the interface to the MAX7219/MAX7221 driver chip; only one MAX72XX object is required for each chain of ...

Electronic paper or ePaper is a display technology that exhibits the appearance of traditional paper. E Ink is a specific brand of ePaper technology, and it has been deployed in various products that ...

This water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

Displays are crucial to modern life; they are literally everywhere. But modern flat-panel LCDs and cheap 7-segment LED displays are, well, a bit boring. When we hackers want to display the progress of ...

Not long ago I wrote an article on TM FAST, a technological module from Siemens, equipped with FPGA, which allows the execution of very fast tasks in parallel to the PLC to which it is connected. The ...

Ah, the age-old problem. You’ve got one oscilloscope, but five engineers want to use it; one telephone line, but three people want to make calls; 20 LEDs, but only eight GPIOs remain on your ...

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 ...
