Electronics Design

Group Assignment:

• Use the test equipment in your lab to observe the operation of a microcontroller circuit board (as a minimum, you should demonstrate the use of a multimeter and oscilloscope

• Document your work on the group work page

1 Weld continuity test

We want to make sure there was no short circuit during welding

To do this, we use a multimeter by taking the option of continuity testing

how is done

## 2 - observation test

to do the test we will flash an LED

materials

  - osciloscope;
  - analyzer;
  - multimeter;
  - Welding magnifying glass;

the code:

 // define led according to pin diagram
 int led = D10;

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

 void loop() {
 digitalWrite(led, HIGH);   // turn the LED on 
 delay(1000);               // wait for a second
digitalWrite(led, LOW);    // turn the LED off
delay(1000);               // wait for a second
    }

obervation

• Observation with the osciloscope

• Observation with the analyzer

  - we had checked the I2C signal for the LCD display
