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

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.
