ARDUINO DRIVERS LICENCE

Lesson 1

Get to know the tools/Make a circuit (14 minute video) https://www.youtube.com/watch?v=2X8d_r0p92U

Estimated time: 20-30 minutes

Concepts

What is a circuit? Ground and power, transducers, circuits in series, current, parallel circuits

t

A simple Circuit that turns the light on when we push the button. Power runs from the 5V (5 volt) on the arduino to the positive (+) rail on the breadboard, up the wire to the pushbutton, when the pushbutton is pressed, it sends power to the LED, through the resistor, back down the wire to the negative rail (-) and back to the GND (ground) pin on the Arduino. Because the LED only needs 1.7 volts, we use the resistor to protect it from getting too much power and burning out.

Extra: Can you make Parallel and series circuits? A circuit in series needs every button to be pressed A circuit in parallel needs only one button to be pressed. When would you use each type of circuit?

Concepts

Servos, if then statements/map function. Trimpot or potentiometer: This type of

component allows us to change the resistance on the component by turning the knob or

screw. A common use for these types of component are volume controls.
