Hi guys, posting after a long time because I ran out of ideas.......
Now lets see how to make a heart rate monitor at home.
Things you need:
1)A computer (with an internet connection)
2)The scope software ----------- Download here
3)An audio cable (3.5mm jack)
4)An Infrared photoresistor
5)Infrared LED
Now lets start making it..........
First download the software and install it in your computer. Then take the audio cable cut the one end and connect the two wires to the infrared photoresistor. Now take the the Infrared LED and connect it to a small battery. Now connect the audio cable with the resistor to your pc's MICROPHONE port
because this software uses the microphone port as the input for the oscilloscope.place your finger between the infrared LED and the resistor now power up the infrared LED now wait for sometime and you can see your pulse being shown on the screen on the graph. You can also use this to check whether there is any block in a pipe or any hallow substance.
