Arduino Uno board
Jumper wiresCode Example
```cpp
// Define the battery voltage and capacity
const float batteryVoltage = 3.7;
const float batteryCapacity = 8000;void setup() {
// Initialize serial communication
Serial.begin(9600);
}void loop() {
// Read the battery voltage
float voltage = analogRead(A0) (batteryVoltage / 1024.0);
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println("V");// Calculate the remaining capacity
float remainingCapacity = (voltage / batteryVoltage) batteryCapacity;
Serial.print("Remaining Capacity: ");
Serial.print(remainingCapacity);
Serial.println("mAh");// Wait 1 second before taking the next reading
delay(1000);
}
```
Example 2: Using the Battery with ESP32 and WiFiIn this example, we will use the Witty Fox 3.7V 8000mAh Li-Ion Battery to power an ESP32 board and connect it to a WiFi network.Hardware RequirementsWitty Fox 3.7V 8000mAh Li-Ion Battery
ESP32 board
Jumper wires
WiFi antenna (optional)Code Example
```cpp
// Include the WiFi library
#include <WiFi.h>// Define the battery voltage and capacity
const float batteryVoltage = 3.7;
const float batteryCapacity = 8000;// Set up the WiFi credentials
const char ssid = "your_wifi_ssid";
const char password = "your_wifi_password";void setup() {
// Initialize serial communication
Serial.begin(115200);// Connect to WiFi
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.println("Connecting to WiFi...");
}Serial.println("Connected to WiFi");
Serial.println("Initializing battery monitoring...");
}void loop() {
// Read the battery voltage
float voltage = analogRead(A0) (batteryVoltage / 1024.0);
Serial.print("Battery Voltage: ");
Serial.print(voltage);
Serial.println("V");// Calculate the remaining capacity
float remainingCapacity = (voltage / batteryVoltage) batteryCapacity;
Serial.print("Remaining Capacity: ");
Serial.print(remainingCapacity);
Serial.println("mAh");// Send the battery data to a server (e.g., ThingSpeak)
WiFiClient client;
client.setServer("http://api.thingspeak.com/update", 80);
client.print("GET /update?api_key=YOUR_API_KEY&field1=");
client.print(remainingCapacity);
client.println(" HTTP/1.1");
client.println("Host: api.thingspeak.com");
client.println("Connection: close");
client.println();
delay(1000);
}
```
Note: Replace `YOUR_API_KEY` with your actual ThingSpeak API key.Safety PrecautionsHandle the battery with care to avoid short circuits or electrical shock.
Avoid overcharging or deep discharging the battery, as this can reduce its lifespan.
Use protective circuitry, such as overcharge protection and short-circuit protection, when designing your device.
Follow proper safety guidelines when working with lithium-ion batteries.
