Easy Pulse Sensor

DIY pulse sensor based on principle of photoplethysmography. Designed for hobby and educational applications to illustrate the principle of photoplethysmography (PPG) as a non-invasive optical technique for detecting cardio-vascular pulse wave from a fingertip. The sensor provides analog PPG output as well as digital pulse output which is synchronous with the heart beat.

Easy Pulse Plugin

Easy Pulse Plugin also provides all necessary instrumentation and amplification on board to detect the cardiovascular pulse signal from the fingertip. The most important characteristics of Easy Pulse Plugin is that it can be easily plugged into the left headers of Arduino Uno (or its compatible clone) board for easy interfacing, and the analog pulse signal can be fed to either A0 or A1 analog input through a 2-pin jumper selection.

Easy Matrix LED display

Easy Matrix is a cascadable 8×8 LED matrix module with the MAX7219 chip on board, which allows to control the display with only 3 I/O pins from microcontroller. Multiple Easy Matrix modules can be easily cascaded to make a bigger-size display through precisely aligned male and female headers on opposite sides of the display.

Multi-purpose power supply

This is a dual-voltage power supply board that provides fixed 3.3V and 5.0V outputs from an unregulated DC input ranging from 7-12V. With its small size (1.8″ X 1.4″), it can be easily enclosed inside a project box along with your project circuit. It uses LM78M05 and LD1117-3.3V fixed voltage regulator chips that are both capable to deliver 500mA of output current.
