Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full brightness. Further, if you hold down the push button ...

Power Supply (5-12V) and External Battery connector The UDOO has been in development for more than a year, and the team says it is "80 percent ready" to deliver the final product.

Instead of the relative horror of driving 40 LEDs with a single Arduino, ... To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based ...

Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

Putting the Arduino inside its own battery pack makes a very neat and compact self-contained unit. At the heart of the board is an ATmega328 clocked at 8MHz to reduce power consumption and fused ...

The mod works using a MAX7219 chip and Arduino Uno ATmega328 board, which control the two 8×8 LED matrixes making up the eyes. Each matrix is wired up to the MAX2719 chip–expect a lot of cables ...
