This website contains numerous information sheets and exercises to enhance the study, understanding and teaching of DESIGN and TECHNOLOGY. – by V. Ryan
The information sheets cover a wide range and include, the design process, gear systems, electronics, cams, printed circuit boards, PIC microcontrollers / computer control.
Topics – RoboLab, PCB Work, Computer Control, PIC Control, Product Design, Electronics, Design Process
Potentiometers are used in circuits, when it is necessary to alter the resistance. Dark/light and temperature sensors usually have these components, as the potentiometer / variable resistor allows the circuit to be made more or less sensitive (they can be turned up or down – reducing or increasing resistance).
