 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.
+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.
