/* 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.

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 ...

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 ...

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

In this tutorial we are going to interface RCWL-0516 Doppler Radar Sensor with Arduino Nano. The RCWL-0516 is a motion detection sensor. It can detect motion through doppler microwave technology ...

Arduino and Seeed Studio have launched the Arduino Sensor Kit Base, an extra large shield for Arduino UNO with 10 modules, and 16 Grove ports.

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.

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 ...
