( Live Wire, Control Studio and PCB Wizard) Objectives: • To introduce teachers to Live Wire, Control Studio and PCB Wizard 3 software • To explore and develop the ‘Live Wire’ software in relation to school based projects and electronic circuit design for Key Stage 3 & 4 • To experience all three software packages in the design and construction of Circuit design and the construction of PCB’s • To develop strategies for teaching this new software at Key Stage 3 and 4 Technology Education Centre 05.
Livewire is a simulated electronics laboratory that uses animation and sound to demonstrate the principles of electronic circuits. Switches, transistors, diodes, integrated circuits and hundreds of other components can all be connected together to investigate hidden concepts such as voltage, current and charge. There are no limits to the circuits that can be designed and no loose connections or faulty components to worry about. However, if the maximum ratings for any components are exceeded, they will explode! Technology Education Centre 05.

Capacitors: A Capacitor stores electric charge. It consists of two plates separated by an insulator called the dielectric. The charge stored depends on the size of the capacitor and the voltage applied to it. The unit of capacitance, the farad, is very large and most capacitors you will use are likely to be measured in microfarads ( F) and nanofarads (n. F). Axial electrolytic capacitor Radial electrolytic capacitor Polyester film capacitor Ceramic disc capacitor Technology Education Centre 05.
When the switch is closed, a current flows into the capacitor until it is full. If R is a resistor with a high resistance the current flows slowly, and if it is a resistor of low value the current flows quickly. Compare this with water from a tap filling a basin. The amount of water flowing into the basin is altered depending on whether the tap is fully open or almost closed. Technology Education Centre 05.
Ex 11 (b): Capacitors Build the circuit as shown press and hold SW 1 and test how long it takes for the voltage meter to reach 9 V using: - a) R 1 = 1 K b) R 1 = 10 K c) R 1 = 100 K Time constant (sec) = C (farads) X R (ohms) Technology Education Centre 05.
Time Constant When the switch is closed and the capacitor starts to charge, the voltage output can be monitored using a voltmeter. To start with the voltmeter will show 0 V, increasing to 9 V when the capacitor is fully charged. A graph can be plotted of the voltage output against the time taken. The first part of the graph is almost a straight line, which then curves and tails off as it takes longer and longer to fill the capacitor. The time taken to reach two thirds of the supply voltage is called the time constant and can be calculated using the formula: Time constant (sec) = C (farads) X R (ohms) Technology Education Centre 05.
The Transistors are semiconductor devices. This means that they have a resistance to the flow of electrons – current. However they become conductors if a small voltage is provided across two of the legs – the base and the emitter. Collector (c) Base (b) Emitter (e) Symbol for the n-p-n transistor You can use the transistor as a high speed switch if a small voltage of 0. 6 – 1. 6 V is applied to the base leg as shown below Technology Education Centre 05.

Ex 12: Potential Divider In the light the voltage between the base and the emitter leg of the transistor is 657 m. V or 0. 65 V. For this transistor the voltage is not enough to switch it on – therefore the bulb remains off. In the darkness the voltage between the base and the emitter leg of the transistor is 739 m. V or 0. 739 V. This voltage is high enough to switch on the transistor – therefore the bulb is switched on. a) Build the circuit shown and test b) Draw the circuit in your folder and explain how it works?

Task: __ Car Radiator Temperature Control: Below is a system designed to monitor the temperature of a car radiator. When the radiator temperature becomes too high the voltage from the temperature sensor and sensor unit changes. The comparator detects this change in voltage and activates the transducer. The transducer driver provides enough power for the motor to operate, cooling the car radiator. Technology Education Centre 05.
Task: __ Conveyor Belt System: The diagram below shows a modular circuit and a conveyor belt system. The circuit has a push switch which, when pressed, causes a solenoid to punch a hole in a piece of card. The card travels across the conveyor belt, is punched and then falls into a basket at the end of the belt. Technology Education Centre 05.
