IDEAL 
FOR GCSE ELECTRONIC
PRODUCTS
Welcome to CIRCUIT BRICKS. This is a system that makes designing circuits simple.
It follows a very common format that most circuits can be modelled around. These circuits are pitched at the required level for most GCSE Electronic Projects.

The circuit "Bricks" are designed for most general applications, but values may
need to be adjusted to suit specific requirements

Pages will change frequently as circuits are developed and updated - Refresh often!


BRICK TYPES CIRCUIT STRUCTURE
INPUTS
  • Sensor - LDR, Thermistor, microphone
  • User Input - switch, potentiometer

PROCESSES

There are many different control devices.
They can be combined to make more complex control systems.
Some basic ones are - comparator, timer, monostable, amplifier, converter, counter

OUTPUTS

  • Audible device - buzzer, siren, speaker
  • Visual device - LED, bulb, 7-seg/dot matrix display
  • Movement - motor, solenoid, meter
Almost all circuits can be broken down into sections, of 3 different types

Many circuits on this site have block diagrams to show their function.
For example, Ultrasonic Alarm, Speed Controller

Most circuits will have many process sections as well as multiple inputs and outputs.
These can all be modelled as shown below.

Try the TUTORIAL to see how to make a freezer alarm.


BRICKS
Below are Circuit Bricks you can use and place together to form a circuit. Just follow these steps:
  1. Write down how you want your design to function - a specification of circuit.
  2. Identify the inputs and outputs and break the control part into stages to form a block diagram.
  3. Look up the circuit for each block using the circuit bricks in the lists below
  4. Connect them together removing duplicate parts and connect up the +V and 0v supplies together.

When you have finished, if you have simulation software (such as Crocdile Clips or Livewire etc.) you can create and test the final circuit out for yourself.
