Jumper wires
Code:
```c
const int ledPin = 13; // Pin 13 for the onboard LED
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
```
Connections:
Connect the positive terminal (red wire) of the battery to the VIN pin on the Arduino Uno board.
Connect the negative terminal (black wire) of the battery to the GND pin on the Arduino Uno board.
Note: Make sure to use a suitable charger to charge the battery, and avoid overcharging or deep discharging to prolong its lifespan.
Example 2: Powering a Raspberry Pi with a Battery Monitoring System
In this example, we will use the 3.7V 1500mAH LiPo Rechargeable Battery to power a Raspberry Pi, and implement a simple battery monitoring system using a voltage sensor.
Raspberry Pi (any model)
3.7V 1500mAH LiPo Rechargeable Battery Model UK-523450P
Voltage sensor module (e.g., ADS1115)
Breadboard and jumper wires
Code:
```python
import RPi.GPIO as GPIO
import time
# Define GPIO pins for voltage sensor
VOLTAGE_PIN = 17
# Set up GPIO mode
GPIO.setmode(GPIO.BCM)
# Set up voltage sensor pin as input
GPIO.setup(VOLTAGE_PIN, GPIO.IN)
while True:
# Read voltage level from sensor
voltage_level = GPIO.input(VOLTAGE_PIN)
# Convert voltage level to percentage
battery_percentage = (voltage_level / 4095) 100
# Print battery percentage
print("Battery level: {:.2f}%".format(battery_percentage))
# Wait 1 second before taking the next reading
time.sleep(1)
```
Connections:
Connect the positive terminal (red wire) of the battery to the power pin on the Raspberry Pi.
Connect the negative terminal (black wire) of the battery to the ground pin on the Raspberry Pi.
Connect the voltage sensor module to the Raspberry Pi's GPIO pins (e.g., GPIO 17).
Note: This code assumes the use of an ADS1115 voltage sensor module, which provides a 12-bit analog-to-digital conversion. You may need to adjust the code to match your specific voltage sensor module.
