1. Getting Started with Arduino IDE Programming

2. Selecting Board Type Selecting Board Type Choosing the port Choosing the port 02 Coding 01 03 void setup() void setup() { } void loop() {} Compile & Upload

3. LED Blinking Program void setup() void setup() { pinMode(LED_BUILTIN, OUTPUT); pinMode(LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); delay(1000); delay(1000); digitalWrite(LED_BUILTIN, LOW); delay(1000); }

4. Serial Monitor Program void setup() void setup() { Serial.begin(11500); Serial.begin(11500); } void loop() { Serial.println(“hello”); }

5. Analog Read Program int analogPin = A0 int val = 0; void setup() { Serial.begin(9600); pinMode(, INPUT); pinMode( analogPin, INPUT); } void loop() { analogRead(analogPin); val = analogRead(analogPin); Serial.println(val); }
