This circuit is a battery-powered system featuring an Arduino Nano that interfaces with a Nokia 5110 LCD and multiple pushbuttons. The TP4056 module charges the 18650 Li-ion batteries, which then power the Arduino through a step-up boost converter. The Arduino controls the LCD display and reads inputs from the pushbuttons for user interaction.

Q: Can the TP5100 charge other types of batteries? A: The TP5100 is specifically designed for lithium batteries and should not be used with other battery chemistries.
Q: Is it possible to adjust the charging current? A: Yes, the charging current can be programmed via external resistors. Refer to the datasheet for the appropriate resistor values.
Q: What does it mean when both the CHG and STDBY LEDs are off? A: This typically indicates that the battery is fully charged and the module has entered standby mode.
// Define TP5100 status pins
const int CHG_PIN = 7; // TP5100 CHG pin connected to Arduino pin 7
const int STDBY_PIN = 8; // TP5100 STDBY pin connected to Arduino pin 8
void setup() {
pinMode(CHG_PIN, INPUT);
pinMode(STDBY_PIN, INPUT);
Serial.begin(9600);
}
void loop() {
// Read the charging and standby status
bool isCharging = !digitalRead(CHG_PIN);
bool isStandby = !digitalRead(STDBY_PIN);
// Output the status to the serial monitor
if (isCharging) {
Serial.println("Battery is charging...");
} else if (isStandby) {
Serial.println("Battery is fully charged and in standby mode.");
} else {
Serial.println("Battery is not charging.");
}
// Wait for a second before reading the status again
delay(1000);
}
This example code for the Arduino UNO reads the charging and standby status from the TP5100 module and outputs the information to the serial monitor. Make sure to connect the CHG and STDBY pins of the TP5100 to the corresponding pins on the Arduino UNO as defined in the code.
