SUNSTEP Training is Technology in Electronics for schools. We provide electrical and electronic kits that is a practical application of theory. Schools visit Sunstep for a workshop in electronics and a presentation at the High Voltage Laboratory of the University of Stellenbosch.

Sasol TechnoX 2017 Secunda Sunstep training was awarded 2nd prize for the exhibition. They also presented workshops on electronics

Sasol TechnoX 2016 Sasolburg Sunstep training was awarded 3rd best exhibition. Sunstep training helped 450 learners to understand electronics better. They were also given the opportunity to solder working electronic circuits.



Electronic systems and control:

Switches: Manual switches controlled by the user, e.g. push, SPST, SPDT, DPDT.

Diodes and LED (Light Emitting Diode): A diode is a component that allows current to flow in one direction only. A LED allows current to flow in one direction only and also gives off light and is often used as an indicator that a circuit is "ON"

Transistors: only npn-type will be used at this level. A transistor is a device that can act as a switch and it can amplify a small current (e.g. from a sensor) into a larger current. Connect a simple transistor circuit.

Sensors - important input devices

LDR (Light Dependant Resistor) - a component whose resistance decreases with light (dark - high resistance; bright light - low resistance).

Thermistor: a component whose resistance varies with temperature. Two types exist:

- +t: resistance increases with increasing temperature.

- -t: resistance decreases with increasing temperature.

Touch or moisture detector: a component that can be bridged using a 'wet' finger, thus completing the circuit, indicating the touch.

Capacitors: a component which can store and then release electrical energy.
