The APDS-9930 is a multifunction sensor that integrates ambient light sensing and proximity detection into a small package. It is applied extensively in use cases such as automatic screen brightness control and touchless interaction systems. In this tutorial, you will learn how to interface the APDS-9930 with an Arduino to sense light intensity and detect … Read more
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
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
Hello, have you ever wanted to control an LED just by making a noise, like clapping your hands? Well, you’re in the right place! In this guide, I’ll show you how to use a sound sensor with an Arduino Uno to make that happen in a super simple way. Don’t worry if you’re new to … Read more
Hello everyone, I was searching the for a simple RF Transmitter-receiver module guide for use in remote control systems like relay controlling or some basic tasks. Unfortunately, I did not find such a guide. Therefore, I wrote a simple article discussing this transceiver, connecting it to Arduino, and programming it. Materials Required Materials Quantity Arduino … Read more
A potentiometer is a simple electronic device that is made up of a resistive wire wrapped around an insulating core and a sliding contact. It can be driven by either a DC or an AC voltage source. The slider movement can be translational (linear), rotational, or a combination of both, and hence it is highly … Read more
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
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
Hey! So, I just bought this super cheap IR remote and receiver kit for Arduino and honestly, it was much easier to use than I thought it would be. The thing is, the documentation for these remotes is a bit sparse, so I decided to figure it out myself and share the steps here. Hopefully, … Read more
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
