step-sequencer

Step Sequencer for Arduino Nano with IR Remote Control - Adjustable Low/High Frequency, Volume and Speed - With 4 Potentiometers

Parts

4 * 100K Potentiometer
2 * 10K Potentiometer
1 Low power consumption speaker ( So it won't require other power source than from the arduino )
1 IR Receiver Sensor
4 Leds + Resistors

Requirements

Soldering
IRremote library
Important:
In order to make the IRReceiver work with the tone() function, you have to change the following 2 lines in boarddefs.h ( Location: Arduino\libraries\IRremote-2.2.3 ):

From:

// Arduino Duemilanove, Diecimila, LilyPad, Mini, Fio, Nano, etc
// ATmega48, ATmega88, ATmega168, ATmega328
// #define IR_USE_TIMER1   // tx = pin 9
#define IR_USE_TIMER2     // tx = pin 3

To:

// Arduino Duemilanove, Diecimila, LilyPad, Mini, Fio, Nano, etc
// ATmega48, ATmega88, ATmega168, ATmega328
#define IR_USE_TIMER1   // tx = pin 9
//	#define IR_USE_TIMER2     // tx = pin 3
