Question

what is the following (ARDUINO):

-Examples of a standard Arduino library

-The Arduino uses a structured programming language-what type

-Channels of A/D conversion on the Arduino Uno

-The Arduino correlates temperature readings with what

Answer 1

Standard Arduino libraries:

->Electrically Erasable PROM(EEPROM): For reading and writing to storage (Non-volatile).

-> Ethernet : For connecting to the internet using the Arduino Ethernet shield

-> Firmata : Uses standard serial protocol for communication with various applications on the host computer

-> GSM: Connectivity to GSM/GPRS network with the GSM shield

-> Servo: For implementing applications which use Servo motors

-> Serial peripheral interface (SPI) bus: For communication with Serial I/O devices

->WiFi: For connectivity to the Internet using the Arduino WiFi shield

Structured programming language:

-> Arduino uses structured programming language (C / C++), which allow Sequencing, Selection and iteration, which are basic elements of structured programming to realize control strcutures.

Analog-to-digital converters(ADC) on the Arduino Uno:

-> Arduino uses 6 ADC channels, which can be used as analog inputs.The ADC is of 10-bit resolution, which means that it will map input voltages between 0 and V_DD volts into integer values between 0 and 1023(2¹⁰-1).So, for N-bit resolution, it is given by: V_DD/(2^N-1)

Correlation of Temperature readings:

-> Temperature readings can be correlated with voltages measured on the analog input pin, with the hep of a function, like analogRead(). Then for conversion the following calibrations or formulae are useful

(i) degreesC = (voltage-0.5) * 100

(i) degreesF = degreesC * (9/5)+32
