Design with Hardware platform in Cirkit DesignerThe ATmega328P Xplained Mini is a compact hardware platform developed by Microchip, designed to evaluate and prototype applications based on the ATmega328P microcontroller. This platform provides a convenient and cost-effective way to explore the capabilities of the ATmega328P, a popular 8-bit AVR microcontroller. It includes essential components such as a USB interface, power supply circuitry, and pin headers for easy access to the microcontroller's I/O pins.
This is a mobile robotic platform with weight sensing and remote control features. It uses an Arduino UNO with a sensor shield to interface with an HX711 weighing sensor module and an L298N motor driver for driving four motors. The platform also includes an IR receiver for remote commands and an LED for status indication.

// Blink an LED connected to pin 13
// Ensure the LED is connected with a current-limiting resistor
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
