Step 2: Simulate an Arduino LED Blink Circuit in Tinkercad
Let’s simulate the most basic Arduino project — an LED blinking circuit.
Components Required (in Tinkercad)
- Arduino Uno R3
- Breadboard
- LED
- 220Ω resistor
- Jumper wires
2.1 Building the Circuit
- Drag Arduino Uno to the workspace.
- Add a Breadboard.
- Connect:
- Arduino GND → Breadboard ground rail
- Arduino Pin 13 → 220Ω resistor → LED Anode (long leg)
- LED Cathode → Breadboard ground rail
Circuit Diagram Preview:
Arduino Pin 13 → Resistor → LED Anode
LED Cathode → GND
2.2 Writing the Arduino Code
Open the Code editor and enter this sketch:
void setup() {
pinMode(13, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH);
delay(1000);
digitalWrite(13, LOW);
delay(1000);
}
2.3 Run the Simulation
- Click Start Simulation.
- Watch your virtual LED blink every second.
Congratulations! You’ve completed your first Tinkercad Arduino Simulation.
Step 3: Simulate a Gas Sensor IoT Warning System in Tinkercad
Next, let’s simulate a basic IoT gas sensor alert system.
Components Required
- Arduino Uno R3
- Breadboard
- MQ-2 Gas Sensor
- LED
- 220Ω resistor
- Jumper wires
3.1 Building the Gas Sensor Circuit
- MQ-2 VCC → Arduino 5V
- MQ-2 GND → Arduino GND
- MQ-2 A0 → Arduino A0
- Connect the LED circuit as earlier.
3.2 Arduino Code for Gas Detection
int gasSensor = A0;
int ledPin = 13;
int threshold = 300;
void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(gasSensor);
Serial.println(sensorValue);
if (sensorValue > threshold) {
digitalWrite(ledPin, HIGH);
} else {
digitalWrite(ledPin, LOW);
}
delay(500);
}
3.3 Test the Simulation
- Click Start Simulation.
- Simulate gas levels by adjusting sensor properties.
- LED turns ON when gas concentration exceeds threshold.
You just created a virtual IoT Gas Sensor Alert System without any hardware!
