Final answer:
The question is about connecting a ULN2003 driver board to an ATmega328 Xplained board for controlling a 28BYJ-48 Stepper Motor. This involves connecting the input leads to the corresponding ATmega board pins, connecting the correct power supplies, and verifying outputs using the built-in LEDs on the driver board.
Step-by-step explanation:
Based on the information provided, it appears you're trying to connect a ULN2003 driver board to the ATmega328 Xplained board to control a 28BYJ-48 Stepper Motor. Start by connecting the four input leads (IN1 - IN4) to the corresponding pins on the ATmega board (PB.0 - PB.3). Connect the ground (-) to the ground input usually denoted by '-' and the 5V power supply to ‘+’ pin. Upon successful connection, you should use the LED outputs on ULN2003 to verify if they're functioning properly before attempting to connect the motor. The LEDs will provide immediate visual feedback on the status of the outputs.
