Example Usage
### Example 1: Powering an Arduino Board
In this example, we will power an Arduino Uno board using the 12V 1A Transformer - 1000mA. We will use a voltage regulator (e.g., 7812) to convert the 12V AC output to 12V DC required by the Arduino board.

```circuitikz
documentclass{standalone}
usepackage{circuitikz}
egin{document}
egin{circuitikz}
draw (0,0) node[transformer] (T) {};
draw (T.1) node:right {230V AC};
draw (T.2) node:right {0V};

draw (VREG.gnd) node[ground] {};
draw (4,0) node[arduino] (ARDUINO) {};
draw (ARDUINO.vcc) node[left] {12V DC};
draw (ARDUINO.gnd) node[ground] {};
end{circuitikz}

```
Code
```cpp
void setup() {
// Initialize Arduino board
}
void loop() {
// Your Arduino code here
}
```
### Example 2: Powering a DC Fan
In this example, we will power a 12V DC fan using the 12V 1A Transformer - 1000mA. We will use a bridge rectifier (e.g., DB107) to convert the 12V AC output to 12V DC required by the fan.
Schematic
```circuitikz
documentclass{standalone}
usepackage{circuitikz}
egin{document}
egin{circuitikz}
draw (0,0) node[transformer] (T) {};
draw (T.1) node:right {230V AC};
draw (T.2) node:right {0V};
draw (T.3) node:left {12V AC};
draw (T.4) node:left {0V};
draw (2,0) node[bridge rectifier] (BR) {};
draw (BR.ac1) node[left] {12V AC};
draw (BR.ac2) node[left] {12V AC};
draw (BR.dc+) node[right] {12V DC};
draw (BR.dc-) node[ground] {};
draw (4,0) node[dc fan] (FAN) {};
draw (FAN.vcc) node[left] {12V DC};
draw (FAN.gnd) node[ground] {};
end{circuitikz}
end{document}
```
Note: In this example, we assume the fan is connected to a suitable power switch or controller to regulate its speed.
