BillPg] has been designing a fantasy 1980s-era home computer. As part of the exercise, he’s reevaluating all the assumptions that have grown organically over time in the small computer ...

A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...

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 ...

Renesas Electronics RA2A2 Arm Cortex-M23 microcontroller (MCU) group offers a 7-channel high-resolution 24-bit Sigma-Delta ADC, as well as dual-bank flash and bank swap function for an easier ...

I did get a number of questions regarding a WiFi option using the Arduino WiFi shield. Initial investigation suggested a lack of memory so to make it fit I had to reduce other functionality. This I ...

The alarm clock you've always dreamed of! Cloc is an original alarm clock. Developed around an ESP32 module, it has functions not found in a commercial product: - Automatic time setting from NTP ...

All microcontrollers have specific numbers of IO pins but in some applications, like in a 7-Segment Display, we will need more GPIO pins than what our controller could offer. For such cases, where ...

Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem, almost every controller comes with an Arduino sleep mode, ...
