Design Of Heart Rate Equipment Base On Bluetooth Communication On Bike Speedometers

A person heartbeat in a minute or so known as a Beat Per Minute (BPM), is one of the indicators of one’s health. Many tools that can help sports activities in cycling, one of the pulse sensors used to be able to detect heart rate. Arduino acts as the brain in this tool. Arduino is powered trough a voltage source of a 9V DC battery. From the voltage source, Arduino will supply the voltage for the pulse sensor and Bluetooth HC05. Pulse sensor will be given voltage by Arduino of 5V and Bluetooth get voltage equal to 3,3 V. When all component have active which will be shown on LCD which applied to handlebar bike.
