Lab: Asynchronous Serial Communications

Preparing the Board

ASCII vs. Binary

ASCII-encoded decimal number

Mapped output to a range from 0 - 255

Sending Data in Multiple Formats

Formatted output, printing raw binary value, then the ASCII-encoded binary value, then the ASCII-encoded decimal, hexadecimal, and octal values.

Changing Serial.println() to Serial.write() sends out binary value of the sensor readings.

Values from Sensors

Formatting multiple serial data using punctuation

Sending values for all three sensors

Using the same concept, formatted data from two analog sensors and one digital switch

Flow Control

Using Terminal’s screen

Using Arduino’s Serial Monitor
