ELECTRICAL - Even biological organisms use electrical signals for control purposes

Electronics is all about fine control of electrical energy. This is to do something useful using electricity other than motive power, heat or lighting. The science of electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive electrical components. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit. We also include here electrical devices such as solenoids, and electric motors, since modern DC machines use electronic controls instead of the mechanical commutator - and batteries and motors need charging regulators and speed controllers.

Electronics is though, distinct from electrical and electro-mechanical science and technology, which deal with the generation, distribution, switching, storage, and conversion of electrical energy to and from other energy forms using wires, motors, generators, batteries, switches, relays, transformers, resistors, and other passive components.

Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. We are concerned with devices that we are likely to use to control our/your DinoBot.

PHOTODIODE SENSORS - Inside your domestic security light you will find these components. We will use the basic idea to make Dino the DinoBot react to guests, but passively. Using these circuits, Dino will be aware of people approaching - and be able to greet them. If the person comes close and speaks to Dino, then Dino will be able to respond audibly, and move its head, or even walk to track the person.

VERSATILE

Almost anything is possible using electronic sensors and controls ....... and then came computers and the digital age ......

REGULATION

Regulation is an important use for electronics ......

SOLAR PANEL CHARGE REGULATORS & DC to DC CONVERTERS - The above is a selection of electronic controllers that will ensure your battery is charged correctly by your solar panels. The lower right is a DC to DC converter to boost voltage should that be needed.
