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
Setting up a touchscreen for your Raspberry Pi is easier than you think and opens up endless possibilities for your projects! In this guide, we will walk you through the connection and configuration of the Raspberry Pi 7″ Touchscreen Display step by step. You could be building a smart home control panel or creating a … Read more
ESP32 Internal Temperature Sensor is basically to calculate the temperature of the ESP32 core. This sensor, however, can’t measure the ambient temperature, that is, atmospheric temperature. For that purpose, we would need to use external temperature sensors like DS18B20, DHT11, BMP280, etc. In this tutorial, we’ll first explore the basics of the Internal Temperature Sensor … Read more
