  1. Maker Uno
  2. House DIY Kit
  3. Mini Breadboard ( 8.5 x 5.5 cm, 400 holes)
  4. Rocker Switch Small 2 pins
  5. Male-to-Male Wire
  6. White LED
  7. Resistor (1 x 220 ohms)
  8. Resistor (1 x 10k ohms)
Steps 

1. Anode(positive) of LED connected to the red wire. While cathode(negative) of LED connected to the black wire.

12. Connect Maker Uno and laptop/pc using USB (like in red circles).

p1 12 

13. Before proceed to this step, Arduino IDE have been installed and some setting is needed.

Note : Follow the step of installation and setup from this website.

After done the installation, copy code from sample code section and paste into Arduino IDE.

To select the board model, go to Tools > Board > Arduino/Genuino Uno.

Click the “Upload” upload button to upload the sample code to your Maker UNO.

Sample Code 

int LED = 4;                              // LED at pin 4
int Button = 2; // Button at pin 2

void setup()
{
pinMode(LED, OUTPUT); // LED as output
pinMode(Button, INPUT_PULLUP); // Button as input
}
void loop()
{
if(digitalRead(Button) == HIGH) // If Button is turned ON
digitalWrite(LED, HIGH); // LED will light up
else if (digitalRead(Button) == LOW) // If Button is turned OFF
digitalWrite(LED, LOW); // LED will not light up
}
