-# Code Club - Mini Band Project
+miniband
+========
-Make your own mini band!
-You and your friends can form your own finger-sized band and rock out using Raspberry Pi and Arduino.
-Learn how to build circuits with sensors and outputs and write a simple programme to control your instruments.
-
-## You will make:
-
-* A guitar
-* A set of drums
-* A pair of maracas
-
-## You will need:
-
-* 1 x Raspberry Pi (plus monitor and power supply)
-* USB hub
-* 2 x Arduino Uno boards (with USB cables)
-* 1 x strip potentiometer
-* 2 x tilt sensors
-* 4 x piezo buzzers (the type in greetings cards, easy to get from Maplin)
-* 10K resistors
-* Bread boards (1 per instrument)
-* Card
-* Sugru (or some other modelling material)
-* Electrical tape
-* Plastic drinking straw
-* Pencil
-
-
-## Software requirements:
-
-* Scratch
-* IDE developer environment for Arduino
-* Py Serial library
-

-## Drum Kit
-
-### 1. Make your drums
-
-Take your 4 piezo buzzers and attach a ring of Sugru (or other modelling material) as shown in the picture.
-This will increase the flexibility and resonance of the sensors. Let the sugru set.
-
-
-### 2. Connect the circuit
-
-Piezo buzzers generate a small charges when you tap them, so they don’t need a power source.
-Connect one lead from your buzzer to one of your analogue inputs, and connect the other lead to ground.
-Repeat for each of your drums. It is easiest to use a bread board for making your circuit.
-Look at the picture for an example.
-
-
-### 3. Progam the Arduino
-
-Find the appropriate code from the respository and upload to your Ardunio board.
-
-
-### 4. Set up in Scratch
-
-Find four different drum sounds (or whatever sounds you'd like your drums to make!). Upload the sounds to Scratch.
-
-
-## Guitar
-
-### 1. Make your guitar
-
-Grab your strip potentiomater, a piece of thin card, and a pencil.
-Lightly draw round your potentiometer on the card and then use this as a guide to draw out your guitar shape.
-(The potentiomater will be the fret board of your guitar).
-Cut out and colour in the guitar and stick down the potentiomater.
-Tape a pencil or stick to the back of the guitar to make it stiffen the fret board.
-
-### 2. Connect the circuit
-
-The potentiomater strip adjusts resistance, so you will need to feed it some electricity.
-Run +5V into one of the strip’s outer pins, and ground into the other outer pin.
-It doesn’t matter which way around you connect these, but it will affect which the direction
-the fretboard runs (high and the top, low at the bottom or vice-versa).
-
-Signal will come from the centre pin, so connect that to one of your analogue inputs and you should be good to go.
-
-### 3. Set up in Scratch
-
-
-
-## Maracas
-
-### 1. Make your maracas
-
-Cut 2 short lengths of drinking straw for your maraca handles.
-Using Sugru (or other modelling material), make 2 maraca heads by rolling it up into balls.
-Push the maraca heads onto the straws and mold into a maraca shape.
-Connect lengths of wire to the connectors of the 2 tilt sensors and then push each sensor into a straw until it presses into the Sugru.
-Leave the Sugru to set.
-
-
-### 2. Connect the circuit
-
-Connect the +5V port on the Arduino board to one of the pins on the tilt switch (it doesn't matter which way round).
-Connect the other pin to an empty digital input on the board.
-
-
-### 3.
-
-
-## Pull-down Resistors
-
-You’ll find your analogue inputs receive signal when you don’t expect them to.
-This is because there’s electricty floating around in the system, or something like that.
-
-To fix this, you need to wire each input to ground, through a 10KΩ resistor.
-
