As more people embrace fitness and exercise, the usage of heart rate monitors has become a popular trend. Heart rate monitors are devices that measure a person’s heart rate while they’re exercising or resting. These monitors provide data that can help individuals maximize their workout intensity and achieve their fitness goals. However, commercially available heart rate monitors can be expensive and may not fit everyone’s budget. A do-it-yourself (DIY) heart rate monitor is an excellent option for fitness enthusiasts who want to save money while keeping track of their heart rate. In this article, we’ll provide you with a step-by-step guide on how to make a DIY heart rate monitor using arduino nano.

Explanation of DIY Heart Rate Monitor
Step 1: Gather materials To make a DIY heart rate monitor, you’ll need the following materials: • An Arduino Nano microcontroller • A breadboard/PCB • A 16×2 LCD display • A photoresistor MAX30102 • Jumper wires • A battery pack.
Step 2: Assemble the circuit Using the jumper wires, connect the LCD display and photoresistor MAX30102 to the Arduino Nano microcontroller and breadboard/pcb. The LCD display will display according to your heart rate, and the photoresistor will sense changes in light intensity.
Step 3: Write the code: Open the Arduino Integrated Development Environment (IDE) on your computer and write the code to make the monitor function. You can find open-source code for this project above in the components list.
Step 4: Test the monitor Once you’ve assembled the circuit and written the code, it’s time to test the heart rate monitor. Put the photoresistor on your fingertip, and your heart rate will be displayed on the lcd displayed attached to it..
Making a DIY heart rate monitor is an excellent way to keep track of your heart rate while saving money. The process is relatively simple and requires only a few materials and basic coding skills. With your new heart rate monitor, you’ll be able to optimize your workout and reach your fitness goals. Give it a try and see the difference it makes!
