Pin Configuration

  • Component Name: 1 Ohm Resistor (Pack of 10)
  • Description: A pack of 10, 1 Ohm resistors, used to limit current flow and divide voltages in electronic circuits.
  • Pin Configuration: A 1 Ohm resistor is a two-terminal component, having two pins.
  • Pinout:
  • Pin 1: One end of the resistor
  • Pin 2: The other end of the resistor
  • Connecting the Pins:
  • To connect the 1 Ohm resistor in a circuit, follow these steps:
  • Step 1: Identify the Pins
  • Identify the two pins of the resistor. Since it's a two-terminal component, there's no polarity (i.e., no positive or negative pins).
  • Step 2: Determine the Circuit Requirements
  • Determine the required connection points in your circuit where the resistor needs to be connected.
  • Step 3: Connect One End (Pin 1)
  • Connect one end of the resistor (Pin 1) to the desired point in the circuit. This could be a positive or negative voltage supply, a signal source, or another component.
  • Step 4: Connect the Other End (Pin 2)
  • Connect the other end of the resistor (Pin 2) to the next point in the circuit, as required by your design. This could be another component, a ground point, or a load.
  • Example Connection:
  • Suppose you need to connect the 1 Ohm resistor in a simple circuit to limit the current flowing to an LED from a 5V power supply.
  • Pin 1: Connect to the 5V power supply
  • Pin 2: Connect to the anode (positive leg) of the LED
  • Important Notes:
  • Ensure the resistor is connected correctly to avoid overheating or damage to the component or the circuit.
  • The 1 Ohm resistor can dissipate a limited amount of power (typically 0.25W or 0.5W). Be sure to check the resistor's power rating and the circuit's requirements to avoid exceeding this limit.
  • Use the correct soldering techniques and handling procedures when connecting the resistor to the circuit board or other components.
  • By following these steps and understanding the pin configuration, you can correctly connect the 1 Ohm resistor in your IoT project or electronic circuit.

Example 1: Voltage Divider with an Arduino
In this example, we'll use the 1 Ohm Resistor as part of a voltage divider to measure a higher voltage using an Arduino.

 Breadboard
 Jumper wires
Circuit Diagram:
R1 (1 Ohm) and R2 (2 Ohm) form a voltage divider, allowing us to measure a higher voltage (Vin) using the Arduino's analog input.
```

Arduino Code:
```c++
const int sensorPin = A0;  // select the input pin for the voltage divider
int sensorValue = 0;      // variable to store the sensor value
void setup() {
  Serial.begin(9600);
}
void loop() {
  sensorValue = analogRead(sensorPin);
  float voltage = sensorValue  (5.0 / 1023.0);  // convert to voltage (assuming 5V Arduino)
  Serial.print("Voltage: ");
  Serial.println(voltage);
  delay(1000);
}
