Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet 'n' simple code,but with a little. ... Here, D11-D10-D9 pins of Arduino is used ...

D9 pin as PWM output; A0 pin as analog input (for current feedback) GND pin just for GND. R - resistor for current measurement (I have 470 Ohm, I think 300-1000 Ohm would be ok, you need to write ...

Pin 2 have a button to ground. Pin 7, 5, A5, A4, A3, A2, A1 and A0 are the outputs, each connecting to an LED through a resistor Fades the D9 pin from 0V to 5V with 0-65535 levels, then back to 0V ...

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

Arduino digital pin headers have an inexplicable 160mil gap between the banks. The Seeeduino has the standard row for shield compatibility, but has an additional row spaced at standard 100mil ...

The LEDs on the 32x8 Dot Matrix Display will react according to the signals that Arduino receives through a microphone that is connected to its analog pin. Arduino has built-in ADC input audio signals ...
