I'm going to continue on electronics.
Basically, electronics is the study of the flow of charge through some materials and devices such as resistors, inductors and capacitors.
Electric systems help in completing tasks such as to control and process data, and conversion and distribution of electric power.
Electronics devices and components is joined together to form a circuit. Electricity is used in people's daily lives, such as switching on the lights for brightness, switching on the heater for warm bathing water and watching television.
Some of the electronic components include,
-wires for connecting
-switch
-resistor
-motor
-battery
-buzzer
These components can be found in electronic circuits.
Circuit diagram is a simplfied pictorial form of electronic circuit. The different components found in the circuit is drawn using symbols. Drawing of circuit diagram help people to draw it easily and save time. It is also easy to see and convenient.
Some electronics circuit are being created by soldering to a printed circuit board.

I am going to blog a bit about electronics.
Electronic devices and components mak up of a electric circuits.
There are many types of circuits, example, Electronic Analog circuits, Digital circuits and Mixed-Signal circuits.
I am going to tell more about the Electronic Analog Circuit.
Some analog electric appliances, example, radio receivers, are made up of a combination of a few basic circuits. Electronic Analog Circuit use a continuous range of voltage.
Analog circuits are sometimes called linear circuits despite that many non-linear effects are used in analog circuits (e.g. mixers, modulators).
Analog circuits and digital circuits are not always easy to differentiate because they both have elements of linear and non-linear operations.
A type of circuit, called "Mixed signal", is analog circuitry that use digital or microprocessor techniques to improve upon the basic performance of the circuit.

Cams are mechanisms that can help to generate movement in mechanical toys. Cams normally work with a cam follower, which is normally a rod made of wood or metal, supported by a shaft that limits the movements and direction of the toy.
Basic principle of cam: To turn in a circular motion in to one that move up and down, which is called reciprocating movement.
In this gravity hammer, the bumps on the turning cam push the end of the lever down and raising the hammer continuously.
