Aided by Arduino Nano and equipped with a keypad, we can make the LED strip flash in different patterns. To design my circuit, I choose a free online EDA tool called EasyEDA which is a one stop design ...

ARDUINO UNO is an ATMEGA controller based board designed for electronic engineers and hobbyists. Arduino based program development environment is an easy way to write the program when compared to ...

This flasher has a chip that controls the random flashing rate of the LEDs. The circuit diagram of the LED flasher using Arduino is shown in Fig. 1. The circuit is built around Arduino Nano board ...

It is a pretty common first project to use an Arduino ... resistor also has to have a sufficient view of the LED. You might use this as a safety light that only works in the dark. A simple circuit ...

Messing around with Arduino can lead to some ... controlling the current in an electrical circuit. This is particularly important if your project uses LEDs, or is complex enough to otherwise ...

Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer. We like how [newsonator] wired up the LEDs to the Arduino by ...

As co-leader of my high school’s Engineering Team, we decided to give the members an Arduino challenge ... fifth start button. All LEDs and buttons are in series with their own resistor. I think that ...
