Pin Plugs:Apin plug, otherwise known as a jumper wire is a simple wire with a single plug on the end that you can use to connect external devices to your Arduino. Each pin plug can connect to one pin on your Arduino. For example, one wire could be connected to pin 13 (which will...
Arduino: How to wire a relay Here's my quick tutorial on how to hook up a relay to an Arduino; specifically an electromagnet switch relay from Omron, the G5SB-14. You can use the relay that's referred to with AC voltage, i.e., to turn on and off mains-powered applications such as...
A how-to on using an I2C LCD display with the ESP32 using Arduino IDE from Random Nerd Tutorials: This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code ...
Use the red wire to connect the VCC from the UART to the VCC on the Arduino Use the black wire to connect the GND from the UART to the GND on the Arduino Use the green Wire to connect the SDA from the UART to the SDA on the Arduino And finally use the yellow wire to connect th...
So now that you know how each numeral can be shown by deciding which LEDs to turn on, let's see how we will wire the 7 segment LED display to the arduino. Before we can do that, we must know the pinout of the 7 segment LED display. In our circuit, we will use a common cathode...
In this tutorial I will show you how I built an Arduino 3D wire bending machine. This is actually a typical mechatronic system because it involves...
As a small hobby project, I'd like to wire this LCD up to a Wifi-equipped Arduino and make a simple NTP-based projection clock. How do I interface with this board? I've never directly interfaced with an LCD before (with no accompanying control circuit), so I'm not sure how to pro...
You can see our main controller, the “Arduino UNO R3”, is responsible for handling signals from IR sensors and doing some computation to calculate the speed of the object. Here in the below picture, you can find our 16x2 LCD display unit, where users can able to see the speed of the...
A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with complete code explanations and tr...
