The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

Of course, this little gadget can’t tell you if you’ve come down with a nasty case of Rigellian fever, but it can read your vitals using a MAX30100 pulse oximeter module and DS18B20 thermometer.

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses.While a Pi can be ...

The OLED display used is a 5-V tolerant type with just four pins: VCC, GND, SDA, and SCL. You can, of course, try an Arduino Nano (v3) instead of the Uno (R3) microcontroller board here without any ...

The combination of a transparent OLED display, Arduino Nano Every microcontroller, HC-05 Bluetooth module, and a small LiPo battery results in a functional and versatile piece of wearable technology.

Snap4Arduino allows us to program an Arduino board in an environment similar to Scratch, which is well known for the ease with which its graphical programming can be done. In this module, you'll learn ...
