Exploring Arduino

1- What do you know about electricity also can we live without it?

2- Usually kids says it power the stuff and it’s all around us.

3- We want the kids to understand that electricity is like water it flows in paths, but we call the particles “Charges”

1- Circuit : is a path for the charges to flow from point to point and it’s a closed one.

2- Circuits look like a circle as if we start from a certain point we will end at the same point again, This why we call it a circuit.

3- In circuits we have two different state, opened circuits and closed circuits.

4- Closed circuits : forms a complete loop with no cuts.

5- Opened circuits : the path is not complete due to one of the wires is not connected or one of the component is corrupt.

Note: we can take advantage of these properties by breaking the power from other component using switches.

1- Circuits do consist of 3 main parts: “Voltage Source, Conductive paths, and Loads”.

2- Voltage source: is the component that provide power to the circuit “Battery”

3- Conductive paths: Is the component that provide routes for the charges to flow from one point to another.

4- Load : is the component in the circuit required to consume the power and make something from for example light bulb consume power to emit light and motor do consume power to move.

1- Current : is the flow of charges at a certain point, Also current carry power from the voltage source to the Load.

2- Also the unit of measuring current called ampere “Amps”, and the device used is the (Ammeter).

3- Voltage: is the amount of pressure power source can provide, Also volts pushes the current to move in wires.

4- The unit of voltage is volts” V”, and the device used is the (Voltmeter).

5- Resistance: is the opposite force in direction to the Voltage, However, every this in life do have resistance.

6- We can mention the unit of resistance which is Ohm” Ω“

Note: We want the participant to know these stuff without mentioning more details.

7- Introduce for them the schematic Diagram, which shows the universal representative for the circuit component.

1- We will use a platform from University of Colorado “PHET Colorado“.

2- Here we want the participant to try making a circuit, also to see how current flows and how increasing the voltage and decreasing it affect the current, in addition to have a look at the resistance and the effect of it increase and decrease.

1 – We will start with an ice breaking question (What is computer? And do you think computer do have a brain? )

.

2- Yes computer do have a brain it’s the (CPU) where all the processing operations happen there.

3- Also computers are devices we used to process data, learn, and play video games.

4- So as computer is quite expensive and needs more power to operate it, so the need come to have a small computer called microcontroller to control some operations and to do specific tasks.

5- After introducing the MCU we will show a quick video to make it easier for the participant to understand the operation in the MCU.

1- Here we will introduce Arduino for the participant, and we will mention some types of the Arduino.

2- Then we will introduce some peripheral that we connect with the MCU to whether collect data or make an action using output devices.

1- Software defined as the collection of data or instructions that tells the computer how to work.

2- The application we used to program the Arduino with is called the (IDE) which translate from the” C” Arduino language to the machine language.
