Pascal Serial Communication With Arduino Code And Enter

Serial data is read from the serial buffer using a sequence of commands like this.

The following is the ASCII table from lookuptables.com, a great source of all sorts of computer-related reference tables.

Pascal Serial Communication With Arduino Code And Enter

Try the following code and enter A in the serial terminal and you will notice that the number 65 is returned to the terminal and output to the screen because the Serial.print() function by default prints the decimal value of the byte.

You can also use an additional argument to tell the Serial.print() function to display the byte using the decimal, hexadecimal, octadecimal, or binary base numeral systems.

The following code will take a byte read in from the serial terminal and print it to the terminal using these various bases.

To help you out, know that strings are defined as follows and are surrounded by quotation marks.

So that whenever I type a alphabet it, it should do a required function linked to it Please help me around.

The raw binary values of those four bytes are 51 (ASCII for 3), 50 (ASCII for 2), 10 (ASCII for newline), and 13 (ASCII for carriage return).

In this lab, youll send data from multiple sensors to a program on a personal computer.

Youll use the data from the sensors to create a pointing-and-selecting device (i.e.

Connect a switch to digital pin 2 like you did in the digital lab.

Use whatever sensors are appropriate to your final application.

While youre figuring what sensors to use, use the most convenient sensors youve got in hand; perhaps two potentiometers for the analog sensors and a pushbutton.

The accelerometers X and Y pins are connected to the Arduinos A0 and A1 inputs, respectively.

The pushbutton is connected from the Arduinos voltage output to pin D2.

The Nano is connected as usual, straddling the first fifteen rows of the breadboard with the USB connector facing up.

Voltage (physical pin 2) is connected to the breadboards voltage bus, and ground (physical pin 14) is connected to the breadboards ground bus.

The other is connected to ground through a 10-kilohm resistor.

The junction between the pushbutton and the resistor is connected to digital pin 2 of the Nano (physical pin 20).

The accelerometer is connected to six rows in the left center section of the board below the pushbutton.

Its Vcc pin is connected to the voltage bus, and its ground pin is connected to the ground bus.

The X axis pin is connected to the Nanos analog in 0 (physical pin 4) and the Y axis pin is connected to the Nanos analog in 1 (physical pin 5).

However, Analog Electronics makes a very popular series of accelerometers, the ADXL3xx series, that have three analog outputs for X, Y, and Z acceleration.

This schematic should work interchangeably for most of them.

Thats because Serial.println() formats the value it prints as an ASCII-encoded decimal number, with a linefeed at a carriage return at the end.

Also, the serial monitor assumes it should show you the ASCII character corresponding to each byte it receives.

The Serial Monitor receives that binary value and assumes it should show you the ASCII character corresponding to that value again.

The garbage characters are characters corresponding to the ASCII values the Monitor is receiving.
