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 ...

to sample the Pulse Sensor with consistent and regular timing. The code is setup to read Pulse Sensor signal at 500Hz (every 2mS). Pulse Sensor Arduino UNO uses Timer2 by default. Use of Timer2 ...

/* These notes put together by Joel Murphy for Pulse Sensor Amped, 2015 The code that this section is attached to uses a timer interrupt to sample the Pulse Sensor with consistent and regular timing.

The makers said that all ages and all skill levels can build the hand-washing timer. In addition to an Arduino Uno, the build includes an HC-SR04 ultrasonic sensor, an SG-90 micro servo motor, three ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The device includes the connection between an Arduino microcontroller and an optical mouse sensor to provide help in reading the movements from horizontal and vertical directions. The Arduino board ...
