In this section of the course we'll be examining two things:
1) Boolean logic
2) Electronics
Boolean Logic
Boolean Logic
Logic gates are primarily implemented electronically using diodes or transistors, but can also be constructed using electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements
These basic elements include:
AND
OR
NOT (inverter)
NAND
NOR
Network Applications
Network Applications
In networks, these often apply as octets pass through logic gates. For example, as the octet 10110010 and the octet 01011011 pass through an OR gate, the resulting table looks like this:

We will be using breadboards as an introduction to electronics in class. We will be using Virtual Breadboard at TinkerCAD to explore basic circuits.
Breadboards
Breadboards
A breadboard is used to make up temporary circuits for testing or to try out an idea. No soldering is required so it is easy to change connections and replace components. As long as you're careful, components will not be damaged so they will be available to re-use afterwards.
Many electronics start their life out on a virtual breadboard of sorts to make sure that the concepts will work before implementation.
The diagram at right shows how the breadboard holes are connected: The red column is the + voltage column. When the "+" voltage (red) linked to the "-" column (0V) through a wire, you've created the most basic circuit (a short-circuit in fact, which will blow out most power supplies or burn out your wire looping + to -, so don't do it).
Additionally, each row is linked horizontally in blocks of 5 holes with a gap in the middle to separate out another block of 5 holes. A typical simple circuit then, would look like the picture at right (of course, the picture at right shows a circuit that to us wouldn't appear to DO anything, but is a complete circuit nonetheless, the current enters the breadboard at left, then proceeds through to the capacitor at right, it then gets looped back down to the left side and returned at the - at the bottom.

Circuit Components:
Before we get much further, various components of a circuit should be explained. The basic parts of a circuit are:
Capacitors: Capacitors store electric charge. They are used with resistors in timing circuits because it takes time for a capacitor to fill with charge. They are also used in filter circuits because capacitors easily pass AC (changing) signals but they block DC (constant) signals
Diodes: Diodes allow electricity to flow in only one direction. The arrow of the circuit symbol shows the direction in which the current can flow. Diodes are the electrical version of a valve and early diodes were actually called valves.
Light Emitting Diodes: When you need to add light to a model, an ordinary filament lamp is the first thing that springs to mind. But if you don't need a high light output, or you need light as an indicator, an LED has many advantages over a lamp.
Relay:
It is often desirable or essential to isolate one circuit electrically from another, while still allowing the first circuit to control the second. One simple method of providing electrical isolation between two circuits is to place a relay between them. A relay consists of a coil which may be energised by the low-voltage circuit and one or more sets of switch contacts which may be connected to the high-voltage circuit.
Resistors:
A resistor placed in a circuit will resist the passage of electrical current through it and will therefore alter the voltages in the circuit according to Ohm's Law
Transformers:
Transformers are used to convert electricity from one voltage to another with minimal loss of power. They only work with AC (alternating current) because they require a changing magnetic field to be created in their core. Transformers can increase voltage (step-up) as well as reduce voltage (step-down).
When placed together, a breadboard circuit may seem daunting, but in reality, if you follow the path of the current logically, you can figure out not only the components in a circuit, but likely the function of a circuit itself. For example, the circuit at left can be simplified in a diagram below:

Using the TinkerCAD, you are to follow along the tutorial posted in Classroom (links below) and submit a snapshot of your final products
1. Read over the attached PDF about electronic components and their symbols.
2. Watch the video - "Introduction to Tinkercad Circuits and Breadboarding".
3. Sign into Tinkercad Circuits using your school Gmail account.
4. Create each of the 4 circuits shown in the Google Doc attached. To share each circuit, click on the "Share" button while the circuit is being simulated and take a snapshot. Insert the snapshot into a Google Doc and submit to Google Classroom. Make sure you use a breadboard with each circuit. (HINT: #4 uses a potentiometer and a DC motor)
Assignment #16- Breadboarding
Assignment #16- Breadboarding
After attending a breadboarding tutorial provided by the teacher, refer to the Tinkercad Learning Circuits document if you need to. Use the Breadboarding Booklet and start on page 8 and complete the following 8 circuits on a breadboard:
Page 7 (the single LED is fine)
Page 13
Page 14 (pick one of the two)
Page 15
Page 16
Page 17
Page 20 note, the dark detector requires a strong light (cellphone flash) to be detected
Page 21
BONUS - Page 23
Submit screen captures of each circuit done in Tinkercad and paste it into a google doc. Include a brief description for each. To exceed expectations, build each circuit using breadboards.Take a picture of each circuit you complete and also include that on your document.
FWIW - The last page of the Breadboarding Booklet has an example of the first circuit (page 7) created in TinkerCAD. You can base all circuits on this one.
