Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In the previous chapter, we used a light sensor to read the ambient brightness as a value from 0 to 1023.This time, we will ...

[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

Last time, we used a light sensor to measure the ambient brightness with an Arduino. When the light hitting the light sensor ...

How much performance can an 8-bit AVR squeeze from addressable LEDs? Assembly, IAR, and GCC reveal the impact on timing, ...

The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop ...

Have you ever wanted to create your own electronic games console? You might be interested in the new DigiPixel Arduino LED game shield which is definitely worth more investigation. The DigiPixel ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
