How to use Weight Sensor with arduino thumbnail

We usually see electronic weighing machines in stores that display weight instantly when an object is placed on the weighing scale. Here, we are going to make a similar weighing machine using an Arduino and a Load Cell that can measure up to 40kg. If needed, it can be increased by using a Load Cell with higher capacity. Load Cell and HX711 Sensor Explained Materials Required: Component Quantity Arduino Uno 1 Load Cell (40kg) 1 HX711 … Read more

How to use a Hall Effect Sensor with Arduino

by
Hall Effect Sensor with Arduino

Hall effect sensor is a sensor whose output is modified by a magnetic field. This means that the output signal it produces is a function of the magnetic field density around it. When the magnetic field is greater than a specified set value, the sensor is able to detect it and generate an output voltage known as the Hall voltage to indicate its detection. Hall Effect Sensor Hall effect sensors are commonly employed due to their versatility. They are typically used … Read more

Atmospheric Oxygen Sensor with Arduino for Room

by
Atmospheric Oxygen Sensor with Arduino for Room

Oxygen sensors are important for saving lives by tracking air quality in hospitals, homes, mines, industries, and laboratories. The convenient sensors also find applications in smart home projects, IoT devices, and so on, and assist in avoiding suffocation hazards in low-airflow areas. In this tutorial, we will explore the DFRobot oxygen sensor, including its features, … Read more

Robot that Follows Lines using Arduino

by
Robot that follow line

As the name indicates, the line follower robot is a computerized vehicle that tracks a visual line marked on the surface. This visual line is a route on which the line-follower robot travels. Typically, it tracks a black line on a white surface, or you can modify it as a white line on a black surface. Students and starters receive their first taste of robotics using this kind of robot. In this project-oriented article, we show you how to create a line follower robot based on Arduino. Line follower robots are applied in … Read more

How to Connect 7-Segment Display to Arduino

How to Connect 7-Segment Display to Arduino

In this tutorial, I will explain how to connect a 7-segment display with 4 digits to an Arduino. Before I start explaining the connection details, I just want to point out a few basic things about this setup. This setup consumes almost all of the digital pins on boards like the Arduino Uno or Leonardo. Most displays have 12 breakout pins that connect either directly to the Arduino or through a resistor. Another thing to mention here is that these displays do not require any connection of Ground, … Read more
