Outline Project: Microduino pulse measuring instrument Objective: Use pulse sensor and Microduino to measure the pulse. Difficulty: High Time-consuming: 5 hours Maker: Microduino Studio-YLB Bill of Materials Microduino equipment Module Number Function Microduino-Core 1 Core module Microduino-FT232R 1 Download program Microduino-OLED 1 Display Microduino-S1 1 Extension board Other equipment pegboard 1 Set up circut 9_Pin Row needles 3 Fix Microduino core Soldering iron 1 welding tool Solder 1 welding tool Wire 1 welding tool tweezers 1 welding tool Document Debug Step 1: Prepare the experiment equipment Step 2: Build adapter board Cut a certain specification size pegboard; Weld the row needles, using VCC(3.3V), GND, A0 abd D6; Make sure the welding position is correct Change the sensore, change the origianl pin to row needles. Weld the sensor port (A0) and LED indictor (D6) Schematic Result OLED using Microduino Cube - S1 to connect, no need weld IIC communication pins (SDA and SCL), but the player can set aside on OLED interface. Step 2: Set up hardware and test whether the welding is correct Assembly Microduino Core, Microdino FT232 and welding board, then power on to check if the sensor indicator light. Step 3：Assembly OLED Download test program Start IDE, open "Microduino_Pulse_measurement" program, compile it and then download: Step 3: Test Put the finger on the sensor, observe whether LED is in a simulated heart beating OLED data can be seen in changes, including the heartbeat, time, times in one minute. From detection to the heart of the first ten seconds is expected to jump how many times in one minute. Result Use the LED to simulate the heart beating. OLED display the heartbeat, time, times in one minute. Issues need to pay attention Weld sensor need more carefully. Can't delete the Interrupt in program.
