Heart Beat Counter
we have built an Arduino based heartbeat monitor which counts the number of heartbeats in a minute. It also displays the output wave form of heart in the form of ECG. Infra Red sensor have two parts one is receiving and the other one is transmitting. It receives the output from the finger and forwards it to the amplifier, that amplifier amplifies the signal and gives it to the comparator, comparator compares the values and forwards it to the arduino. In addition to that, an oscilloscope is attached to output of sensor which will act as ECG monitor. It is a portable device which can be used anywhere.
