The document discusses Arduino boards and programming. It introduces microcontrollers and Arduino boards, which contain a microcontroller, power supply, USB port, and memory. It then covers Arduino programming concepts like data types, operators, control statements like if/else and switch/case, loop statements like for, while and do/while loops, and the basic code structure of setup() and loop() functions. Finally, it provides an example of a basic blinking LED program.

Control Statements
• If Statement
if (condition1) {
// block of code to be executed if condition1 is true
} else if (condition2) {
// block of code to be executed if the condition1 is false and
condition2 is true
} else {
// block of code to be executed if the condition1 is false and
condition2 is false
}

for (statement 1; statement 2; statement 3) {
// code block to be executed
}
2. While
while (condition) {
// code block to be executed
}
3. Do while
do {
// code block to be executed
}
while (condition);

Code Structure
Void setup(){
Used to indicate the initial values of the
system on starting
}
Void loop(){
contain the statements that will run
whenever the system is powered after setup
}
