Page 6: The Design Process
Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 The Design Process The design process can be short or long, but will always consist of a number of Design Brief steps that are the same on every project. By splitting a project into these clearly defined steps, it becomes more structured and manageable. - Page 7 Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 The Design Brief A manufacturer of childrens toys has designed a circuit that plays a tune when a switch is opened or closed. The manufacturer can think of many great applications for this circuit.

Take it in turns to review each person s design against the requirements of their specification. Also look to see if you can spot any additional aspects of each design that may cause problems with the final product.
- Page 12 Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 Soldering in Ten Steps 1. Start with the smallest components working up to the taller components, soldering any interconnecting wires last. 2. Place the component into the board, making sure that it goes in the right way around and the part sits flush against the board.

Page 13: Resistor Values
Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 Resistor Values A resistor is a device that opposes the flow of electrical current. The bigger the value of a resistor, the more it opposes the current flow. The value of a resistor is given in (ohms) and is often referred to as its ‘resistance’. - Page 14 Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 Calculating resistor markings Calculate what the colour bands would be for the following resistor values. 1st Band 2nd Band Multiplier x alue 3,900 47,000 (47K) 1,000,000 (1M) What does tolerance mean? Resistors always have a tolerance but what does this mean? It refers to the accuracy to which it has been manufactured.
- Page 15 Programmable Music Box Teaching Resources www.kitronik.co.uk/2122 Why Use a PIC Micro-controller? There are a number of advantages to using a micro-controller, some of these are outlined below: Complex functionality can be produced at very low cost. Circuit size can be very small and still provide complex functionality.

Page 20: Build Instructions
Programmable Music Box Essentials www.kitronik.co.uk/2122 Build Instructions Before you start, take a look at the Printed Circuit Board (PCB). The components go in the side with the writing on and the solder goes on the side with the tracks and silver pads. - Page 21 Programmable Music Box Essentials www.kitronik.co.uk/2122 Checking Your Music Box PCB Check the following before you insert the batteries: Check the bottom of the board to ensure that: All the pads with wires in them are properly soldered. Pins next to each other are not soldered together.

Where the micro-switch will be mounted (bottom right). Where the sounder will be mounted (right).
- Page 24 The test program referenced in the ‘Testing the PCB’ section can be downloaded from the resource section of the Kitronik website at the web address listed at the bottom of this page. We would suggest that you program a chip with this test software.
- Page 25 Programmable Music Box Essentials www.kitronik.co.uk/2122 How the Music Box Hardware Works The music box is based around an eight pin PIC micro-controller device. A PIC is, in effect, a small computer that behaves in a way determined by the software that it’s programmed with. This software is generated by the user / student.
