ARDUINO LANGUAGE SERIAL
The monitor decodes and displays that serial bitstream as the “Hello!” message.Īfter the setup function is done, the Arduino automatically skips to the loop function and starts doing what the statements in its curly braces tell it to do.
ARDUINO LANGUAGE SERIES
This tells the Arduino to send a series of binary ones and zeros to the Serial Monitor. Serial.print( val) passes the message “Hello!” to the val parameter. That’s 9600 binary ones or zeros per second, and is commonly called a baud rate. This tells the Arduino to get ready to exchange messages with the Serial Monitor at a data rate of 9600 bits per second. Serial.begin(9600) passes the value 9600 to the speed parameter. The sketch provides these values inside parentheses in each function call. Here, speed and val are parameters, each describing a value that its function needs passed to it to do its job.
ARDUINO LANGUAGE CODE
In this example, both statements are function calls to functions in the Arduino’s built-in Serial pre-written code library: Serial.begin( speed) and Serial.print( val). The Arduino executes the statements you put between the setup function’s curly braces, but only once at the beginning of the sketch. The Arduino language has two built-in functions: setup and loop. Modulus AND assignment operator.A function is a container for statements (lines of code) that tell the Arduino to do certain jobs. It divides left operand with the right operand and assign the result to left operand It multiplies right operand with the left operand and assign the result to left operandĭivide AND assignment operator. It subtracts right operand from the left operand and assign the result to left operand It adds right operand to the left operand and assign the result to left operand
Increment operator, increases integer value by oneĭecrement operator, decreases integer value by oneĪdd AND assignment operator. The left operands value is moved right by the number of bits specified by the right operand. If a condition is true then Logical NOT operator will make false.Īssume variable A holds 60 and variable B holds 13 then −īinary AND Operator copies a bit to the result if it exists in both operands.īinary OR Operator copies a bit if it exists in either operandīinary XOR Operator copies the bit if it is set in one operand but not both.īinary Ones Complement Operator is unary and has the effect of 'flipping' bits.īinary Right Shift Operator. Use to reverses the logical state of its operand. If any of the two operands is non-zero then then condition becomes true.Ĭalled Logical NOT Operator. If both the operands are non-zero then then condition becomes true.Ĭalled Logical OR Operator. Modulus Operator and remainder of after an integer divisionĬhecks if the value of two operands is equal or not, if yes then condition becomes true.Ĭhecks if the value of two operands is equal or not, if values are not equal then condition becomes true.Ĭhecks if the value of left operand is greater than the value of right operand, if yes then condition becomes true.Ĭhecks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true.Ĭalled Logical AND operator. Stores the value to the right of the equal sign in the variable to the left of the equal sign. C language is rich in built-in operators and provides the following types of operators −Īssume variable A holds 10 and variable B holds 20 then − An operator is a symbol that tells the compiler to perform specific mathematical or logical functions.
