Stages of DIY electronics design

You get an idea! Prototype Schematic +PCB design

PCB Manufacture

What we’re making

Electric circuit

“An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of "flow," just like the flow of a liquid through a hollow pipe.

The force motivating electrons to "flow" in a circuit is called voltage. “http://www.allaboutcircuits.com/vol_1/chpt_2/1.html

Electricity

Resistance, Voltage, Current

Resistance

Resistance is the hindrance to the flow of charge.

Voltage

Voltage is the force or pressure that excites the electrons to flow.

Current

Current is the rate of the electrical charge passing through a point on a circuit, measured as a quantity over time.

Demo: Using a multimeter

Demo: Generating power
