Pulse-width modulation (PWM) Pulse width modulation (PWM) is a powerful technique for controlling analog circuits with a microprocessor’s digital outputs. Pulse-width modulation,as it applies to LED ...

How It Works The LDR is connected to a voltage divider circuit to produce an analog signal proportional to the light intensity. The analog signal is read by the Arduino via pin A0. The program ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

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 ...

Our programming magic will make all this work smoothly. The below image show the 4x4x4 LED Cube Arduino Simulation, you can see how each pin on arduino nano is able to control the LEDs on our cube ...

Status ###########--Work in progress--########## Simple Arduino Code to read the Time from a DS3231 RTC Device and distribute it to a selfmade LED-Matrix. ToDo: add drawings for the matrix and the ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Each connection to the Arduino I/O drives an LED anode, while the cathodes are joined between the diodes of each plane and go to lines A, B, C, and D, which will be cycled to logic low. So, as far as ...
