Atmega328P is pre-programmed with _____. This allows you to directly upload a new program into the device, without using any external hardware programmer, making it easy to use.

bootloader

The Arduino UNO board has _____ analog _____ , labeled “ 0 to 5.” These pins can read the _____ from an _____ sensor like a temperature sensor and convert it into a digital value so that the system understands. These pins just measure _____ and not the current because they have very high _____ _____. Hence, only a small amount of _____ flows through these pins. These pins can also be used for digital _____ or _____.

6; input pins; analog; signal; analog; voltage; internal resistance; current; input; output

You can find _____ _____ labeled “_____ 0 to 13.” These pins can be used as either _____ or _____ pins. When used as output, these pins act as a power supply _____ for the components connected to them. When used as input pins, they read the _____ from the component connected to them.

digital pins; digital; input; output; source; signals

When digital pins are used as _____ pins, they supply _____ milliamps of current at _____ volts, which is more than enough to light an LED.

output; 40; 5

Some of the digital pins are labeled with _____ (~) symbol next to the pin numbers (pin numbers _____, _____, _____, _____, _____, and, _____). These pins act as normal digital pins but can also be used for _____ _____ _____ (PWM), which simulates _____ output like fading an LED in and out.

tilde; 3, 5, 6, 9, 10, 11; pulse-width modulation; analog

When the _____ button is clicked, it sends a logical pulse to the reset pin of the microcontroller, and now runs the program again from the _____. This can be very useful if your code doesn’t repeat, but you want to test it multiple times.

reset; start

The _____ _____ steps down the 9 to 12 volt input power to _____ volts, which is the operating voltage of the Arduino.

voltage regulator; 5

The _____ _____ _____ (_____ - _____) light up whenever data is transferred between Arduino and your computer. _____ _____ indicator blinks when Arduino sends signal to the output component, while _____ _____ indicator blinks when the board receives a signal from sensors.

The _____ _____ can be used to supply electrical power from _____ to _____ respectively. The _____ _____ were used to ground _____ _____ (mostly _____ charges).

power pins; 3.3V; 5V; ground pins; electrical supply; negative

A _____ is a device used in creating and testing simple circuits in electronics. It connects multiple points instead of soldering them together, making it easy to re-create and disassemble.

breadboard

Breadboard many years ago were made using a piece of _____ or _____ used in cutting _____ of _____. Wires are being bind together using _____ and , to create a circuit. Since then, electronic components became smaller and smaller, that’s why we created a modern “” board using the same iconic name.

wood; plank; loaves; bread; thumbtacks; pins; solderless

All holes in the _____ of the breadboard are internally connected. In the middle of the breadboard, we can see a _____. This divides the breadboard into two parts. Holes from the _____ part of the breadboard are not _____ to the holes at the other side.

middle; divider; upper; connected

At both edges of the breadboard, we can see the _____ _____ that is connected internally. When building a circuit, you tend to need power in lots of different places. These give you lots of easy access to power, labeled as positive and negative.

power rails

LED or _____ _____ _____ converts _____ into _____ and looks like a tiny lightbulb. They require a lot _____ power to light up. They’re _____ efficient, so they don’t tend to get _____ unless you supply them with a high _____ supply. This makes them ideal for _____ devices and other _____ applications.

light emitting diode; energy; light; less; energy; hot; voltage; mobile; low-power

In electronics, _____ indicates whether a circuit component is _____ or not. LEDs, being _____, will only allow current to flow in _____ direction. And when there’s no current flow, there’s no light. Luckily, this also means that you can’t break an LED by plugging it in backwards - it just won’t work.
