Code Examples
### Example 1: Charging a Li-Ion Battery with Arduino
In this example, we'll use the TP4056 module to charge a Li-Ion battery using an Arduino board.
Hardware Requirements
Arduino Board (e.g., Arduino Uno)
 TP4056 1A Li-Ion Battery Charging Protection Module
 Li-Ion battery (e.g., 3.7V 600mAh)
 USB cable
Code
```c
const int chargePin = 2;  // Pin for indicating charging status
void setup() {
  pinMode(chargePin, OUTPUT);
  digitalWrite(chargePin, LOW);  // Initialize charging status pin as low
}
void loop() {
  if (digitalRead(chargePin) == LOW) {  // Check if charging is in progress
    Serial.println("Charging...");
  } else {
    Serial.println("Charged or not charging");
  }
  delay(1000);
}
```
Note: In this example, pin 2 of the Arduino board is used to monitor the charging status. When the charging is in progress, the chargePin will be low. When the charging is complete or not charging, the chargePin will be high.
### Example 2: Using the TP4056 Module with a Solar Panel and a Load
In this example, we'll use the TP4056 module to charge a Li-Ion battery using a solar panel and power a load (e.g., an LED).
Hardware Requirements
TP4056 1A Li-Ion Battery Charging Protection Module
 Li-Ion battery (e.g., 3.7V 600mAh)
 Solar panel (e.g., 6V 1W)
 Load (e.g., LED with a resistor)
 Jumper wires
Connection
Connect the solar panel to the IN+ and IN- pins of the TP4056 module.
 Connect the Li-Ion battery to the B+ and B- pins of the TP4056 module.
 Connect the load (e.g., LED with a resistor) to the OUT+ and OUT- pins of the TP4056 module.
No code is required for this example, as the TP4056 module will automatically manage the charging and discharging of the Li-Ion battery based on the input voltage from the solar panel.
Caution: Ensure that the input voltage from the solar panel does not exceed the maximum input voltage rating of the TP4056 module (6.5V).
By following these examples, you can effectively use the TP4056 1A Li-Ion Battery Charging Protection Module in various IoT projects, such as solar-powered systems, sensor nodes, and wearable devices.
