Off-grid Solar PV Panel project

Building a small scale Solar PV system using an Arduino

• Arduino fan motor control

Arduino IDE Installation and Configuration on a Raspberry Pi

Arduino LED Blink Program

• Program lights up Arduino UNO on-board LED connected to pin 13 for 1 second.

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

*/

// the setup function runs once when you press reset or power the board

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level) = 1 = 5V supply
  delay(1000);                       // wait for 1 second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW = 0 = 0V supply
  delay(1000);                       // wait for 1 second
}

Arduino UNO - Building a LED Blink Circuit on a Breadboard

• Build an external LED Blink Circuit for the Arduino UNO.

Arduino UNO - Building a Mini-Solar PV Circuit

• Demonstration on how to build a small PV circuit that charges a battery on an Arduino UNO.
• The circuit incorporates a Voltage Divider circuit.
