Desolder Pump Documentation
The Desolder Pump is a type of vacuum pump used to remove solder from electronic components and printed circuit boards (PCBs) during the desoldering process. This component is commonly used in electronics repair, prototyping, and manufacturing industries.
The Desolder Pump typically has three pins:
VCC (Positive Power Supply)
GND (Ground)
SIG (Signal/Control Pin)
The Desolder Pump can operate in two modes:
Manual Mode: The pump is activated by applying a logic high signal to the SIG pin.
Auto Mode: The pump is activated automatically when the SIG pin is connected to a microcontroller or other control device.
### Example 1: Manual Mode using Arduino
In this example, we will demonstrate how to use the Desolder Pump in manual mode with an Arduino board.
```cpp
const int pumpPin = 2; // SIG pin connected to digital pin 2 on Arduino
void setup() {
pinMode(pumpPin, OUTPUT);
}
void loop() {
// Activate the pump by setting the SIG pin high
digitalWrite(pumpPin, HIGH);
delay(1000); // Pump activated for 1 second
digitalWrite(pumpPin, LOW);
delay(1000); // Pump deactivated for 1 second
}
```
### Example 2: Auto Mode using Raspberry Pi (Python)
In this example, we will demonstrate how to use the Desolder Pump in auto mode with a Raspberry Pi using Python.
```python
import RPi.GPIO as GPIO
import time
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Define the SIG pin
pump_pin = 17
# Set up the SIG pin as an output
GPIO.setup(pump_pin, GPIO.OUT)
while True:
# Activate the pump
GPIO.output(pump_pin, GPIO.HIGH)
time.sleep(1) # Pump activated for 1 second
# Deactivate the pump
GPIO.output(pump_pin, GPIO.LOW)
time.sleep(1) # Pump deactivated for 1 second
```
### Example 3: Using the Desolder Pump with a microcontroller (C)
In this example, we will demonstrate how to use the Desolder Pump with a microcontroller (e.g. ATmega328P) using C code.
```c
#include <avr/io.h>
#define PUMP_PIN PORTB2 // SIG pin connected to PORTB2
int main(void) {
DDRB |= (1 << PUMP_PIN); // Set PUMP_PIN as an output
while (1) {
PORTB |= (1 << PUMP_PIN); // Activate the pump
_delay_ms(1000); // Pump activated for 1 second
PORTB &= ~(1 << PUMP_PIN); // Deactivate the pump
_delay_ms(1000); // Pump deactivated for 1 second
}
return 0;
}
```
Note: In all examples, ensure the Desolder Pump is properly connected to the power supply and the control device (e.g. Arduino, Raspberry Pi, microcontroller). Additionally, always follow proper safety precautions when working with electrical components.
