Programming a traffic-light with arduino

Good morning.

Today we have made a traffic-light with arduino.


Materials

• 3 LEDS
• 220 Ohms Resistor
• Wires
• Arduino
• Breadboard

First the green LED will light up, then the yellow LED and finally the red LED, the process will be repeated indefinitely.

First microcontroller program - Blinker

Hi

Today I present you the first program with the Arundino microcontroller.
For this practice we used:

1. LED diode
2. Cables
3. A resistance of 220 Ohms. (Not to burn the LED)
4. An Arduino microcontroller.

Steps:

1. We connect the positive of the LED to the 0 port of the Arduino.
2. Connect the negative of the LED to the resistor.
3. Finally the resistance to the GND port of the Arduino.
4. We program by blocks so that the positive in the zero port opens 1 second, then closes 1 second, the program will be repeated infinitely, so the LED will be flashing.

Parallel Circuit versus Series Circuit

Hi.

Today I'm going to show you a parallel circuit vs a series circuit.

Components:

• 9V batteries.

• Cables.
• Motors.
• Lightbulbs.
• Multimeters.

In the parallel circuit the motor is faster and the lightbulbs are brighter.

Two circuits with multimeters to observe the electrical parameters

Hi!!

Today we have practice making circuits with tinkerkad.

Electrical definitions:

• ELECTRICITY: The flow of electrons from negative to positive pole in a conductor.

• VOLTAGE: That force which is generated to cause current to flow in an electrical circuit. Voltage is measured in Volts "V".

• INTENSITY OF THE CURRENT: Flow of electricity along a surface of conductor in a time. Current is measured in Amperes "A" = Coulombs/sg. 1 Coulomb= 6.242×10¹⁸electrons.

• MULTIMETER: A testing device that can be set to read ohms (resistance), voltage (force), or amperes (current) of a circuit.

In the following circuits, we can see how the electrical parameters vary, when only the voltage or force of the battery changes. The circuit with the lower voltage battery will look less and have less intensity.

Programming moana

Today we show you a new web site to practice programming with blocks.

Join Moana (Vaiana in Spanish) and Maui in an adventure game while learning all about loops, conditionals and the fundamentals of code. It is your Hour of Code!

Our fist circuit

Hello!

Today we have made a simulated circuit with tinkerkad.

The elements of the circuit were:

1. Battery.
2. Wires.
3. Lightbulb.
4. Pushbutton switch.

Operation: The electrons leave the negative pole attracted by the positive pole, in the filament of the bulb they collide producing heat by friction, then the filament becomes bright red, giving light.
