Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

Two Push buttons with pull-down resistors of 10K are connected to the Arduino pins 2 & 4, and an LED is connected to PIN 7 of Arduino through a 2.2K resistor. The setup will look like the image below.

A simple 7x5 LED matrix circuit using Arduino Uno (Arduino LED Project). It can be used to create any number of patterns or display your name.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

We previously used multiplexing technique in Arduino to interface 4-digit 7-segment display and driving 8x8 LED matrix. Charlieplexing allows you to control N * (N – 1) LEDs, where N is the no of pins ...

There are two kinds of people in the world (and, no, this isn’t a binary joke). People who love the Arduino, and people who hate it. If you’ve ever tried to use a standard prototype boa… ...

digitPins is an array that stores the arduino pin numbers that the segments are connected to. Order them from segment a to g , then the decimal place. The bottom line should read - segmentPins is an ...

This is a tool that allows you to control your Arduino pins with your serial-console. Typing in read or READ will ask you for a pin number and then will return the current state of this pin. Writing ...
