1 Presentation overview Engaging electronics for the new D&T curriculum Geoff Hampson Managing Director of Kitronik What to include Free web resources Electronic project ideas Using programmable components Adding electronics to textiles Why choose Kitronik Tips on delivering engaging electronics Teaching notes Allow teachers with limited knowledge to use the kits Build instructions Fault finding flow charts Circuit explanations Quality PCBs Free resources Free technical support Free samples Typically over 99.5% of lines in stock and ready for next day dispatch Make the theory interactive Clipping parts together Multi-choice quiz Select an exciting project Fuse tester, plant moisture sensor Amplifier, night light, travel game Allow for creativity with the enclosure design Programme of study New programme of study The study of making in systems and control should include: n the practical application of systems and control in design proposals o electrical, electronic, mechanical, microprocessor and computer control systems and how to use them effectively p using systems and control to assemble subsystems into more complex systems q feedback and how a variety of inputs can give rise to a variety of outputs. Technical knowledge understand and use the properties of materials and the performance of structural elements to achieve functioning solutions understand how more advanced mechanical systems used in their products enable changes in movement and force understand how more advanced electrical and electronic systems can be powered and used in their products [for example, circuits with heat, light, sound and movement as inputs and outputs] apply computing and use electronics to embed intelligence in products that respond to inputs [for example, sensors], and control outputs [for example, actuators], using programmable components [for example, microcontrollers]. Design and technology programmes of study: key stage 3 1

6 Ease of use 09/05/2014 Where do we find microcontrollers? Why use a microcontroller? Timer implemented using conventional hardware Timer implemented using a PIC Microcontroller options Comparison of control options PICAXE / Genie Arduino Raspberry Pi Hard Cost PICAXE & Genie Raspberry Pi Inputs / outputs Programming Flowchart, basic C, flowchart C, Python, Scratch Easy Arduino Uno System capability Using PICs in schools Getting started PIC with special boot strap code Programming editor Software written using flowcharts or basic code Logicator Software developed on a PC Cheap interconnecting cable Board with special connection Genie 6

7 Programming connector 09/05/2014 Programming connections PIC kits 5v PICAXE Kitronik Genie 0v PIC boards Features Use any 8 pin microcontroller, the stereo jack is compatible with PICAXE chips & most educational software Two inputs, complete with pull down resistors, ready for switches to be connected directly to the board Test button switches on the two inputs for ease of software testing Development Project PIC development board Reusable board for students to try out their ideas PIC project board A board for students to build and use in their projects Outputs 1 & 2 directly driven by the PIC, max current 25mA Output 3 transistor driven, max current 800mA Debug LEDs, allowing ease of software testing. These are low current LEDs and only consume 2mA, leaving plenty of current for the peripheral. Terminal blocks for easy connection of devices Block diagram Selecting input & output devices Development board Input devices Output devices Input 1 Input 2 Test switch Test switch Pull down resistor Pull down resistor Project board PIC Debug LED Debug LED Output 1 (up to 23mA) Output 2 (up to 23mA) Debug LED Output 3 (up to 800mA) Miniature push button Vibration switch Pressure mat LED Piezo buzzer Input 1 Input 2 Pull down resistor Pull down resistor PIC Output 1 (up to 25mA) Output 2 (up to 25mA) Output 3 (up to 800mA) Tilt switch Micro switch Potentiometer LDR DC Motor MES Lamp 7
