MIDI Volume Controller
This is a simple MIDI project, utilizing the Miduino
design, to output a MIDI Volume control signal when a foot
pedal variable potentiometer is adjusted.

The MIDI Volume Controller unit utilizes:
- A Miduino kit including a
suitable pre-programmed Atmega168,
- A 2.1mm power socket, and associated LED,
- A 4-way DIP switch, which selects the MIDI channel at power-on, shown
in table 1
- A MIDI 5-pin DIN output socket,
- 0.1" pin-terminal inputs/outputs,
- The circuit schematic is
available,
- The jack socket wiring diagram is
available,
- MIDI available/transmit LED
The MIDI Volume Controller also requires:
- A 9v battery or equivalent DC power source
- A 10k linear potentiometer
Operation:
A MIDI Volume control signal is transmitted when a foot pedal
variable potentiometer is adjusted. This MIDI command is channel (1-16) dependent.
The MIDI channel, that the volume controller affects, is set by
the 4-way DIP switch selection, shown in Table 1 below.
Circuit Schematic:
A circuit schematic of the Miduino
shows the Input/Output connections. The Miduino is designed to
connect to external breadboards or matrix boards on a 0.1"
grid.
Assembly:
The kit
includes all parts necessary, the assembly is straightforward and
well documented. This design does not include a USB chip, it is
designed to use a FTDI
USB 232-TTL cable to program the microcontroller. However since the cable plugs
directly into
the Miduino, you can use one cable for multiple Miduinos.
MIDI Wiring:
The MIDI OUT connector uses a 5-Pin 180 degree DIN
sockets. Note that the MIDI IN/OUT wiring
is polarised and the correct pins should be used.
Download:
Open the source
code file and copy and paste it into the Arduino programme and
save it as a .PDE file.
