Robot that Follows Lines using Arduino

January 26, 2025 by smith

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 Read a TV Remote with Arduino

January 17, 2025 by smith

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

How to Connect 7-Segment Display to Arduino

January 16, 2025 by smith

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

Measuring & capabilities ESP32 with Inbuilt Temperature Sensor

January 1, 2025 by smith

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

How to Use OLED as an Arduino Serial Plotter

December 26, 2024December 25, 2024 by smith

Most Arduino owners, at some point, want to output text or results to a screen for their projects. Most of these begin with the use of a two-line LCD because they’re readily available, cheap, and have tons of example programs already available. It uses most of your digital I/O lines and only prints text- no graphs, shapes, or icons. The small yet versatile SSD1306 OLED measures diagonally only at 0.96 inches. It is a mono digital display using only two pins (SCL and SDA) to communicate, perfect for graphing or displaying geometrical shapes. You can power it directly from the Arduino with 5V … Read more
