Arduino Projects for Beginners:

Water Flow Rate & Volume Measurement using Water Flow Sensor & Arduino “Fluid Flow Rate Sensor”



The Water Flow Rate Sensor can be used in so many amazing projects. You can make your own water/liquid volume measurement system which is only possible if you know about the basics of the Water Flow Sensor.

In this tutorial, you will learn how to accurately measure the Water Flow Rate and Water volume using the Water Flow Sensor YF-S401, Arduino UNO, and a 12v DC Water Pump.

Working on the Water Flow Sensor is a bit tricky whether you are using YF-S401 or YF-S201 Hall Effect Water Flow Sensor, and that’s the reason, most of the people complain about the wrong values. There are things that we need to take care of while using the Water Flow Sensor.  As per the datasheet, when water flows through the rotor, rotor rolls. Its speed changes with different rates of flow. If we can keep the pressure and flow constant we can make an accurate water volume measurement system. I solved this problem by using a 12v Water Pump.

In this tutorial, I have explained what’s inside a Water Flow Sensor and how it works. I have also explained the complete circuit diagram, making, and Arduino programming.

MPU6050 Arduino Wiring, Library, and Code to find the Angle “GY-521”

The MPU6050 gyroscope sensor one of the most frequently used sensors throughout the world. I believe every beginner should learn about the MPU6050. Using the MPU6050 sensor, you can build a self-balancing robot, a self-balancing bicycle, a hand gesture controlled robot, a self-balancing platform for a Camera, you can control an onscreen 3d model with this sensor, etc. The MPU6050 sensor can be used in thousands of projects, but it is only possible if you know about the extreme basics, like its wiring with the Arduino and Arduino Programming.

Arduino RTC DS3231 Time and Date display on a 16×2 LCD “Real Time Clock”


The RTC DS3231 Real Time Clock is one of my most favorite electronic components. This is the most accurate Real-Time Clock and I believe every beginner should learn how to use the RTC DS3231. You can build beginner and advanced level projects using this Real-Time Clock. You can make an Automatic School Bell, you can build a Sensor monitoring system which displays the sensor data with date and time information, you can make an automatic load management system using RTC DS3231, etc.
