Build an Arduino in a breadboard

Wiring Instructions

To wire ATmega328 to your project, connect the following pins:

• ATmega328 Pin 9 –> Crystal Pin 1 –> Ceramic Capacitor 22pF Pin1 (1st Capacitor)
• ATmega328 Pin 10 –> Crystal Pin 2 –> Ceramic Capacitor 22pF Pin1 (2st Capacitor)
• The other Pins of Capacitor to GND
• ATmega328 Pin7 –> +5V
• ATmega328 Pin20 –> +5V
• ATmega328 Pin21 –> +5V
• ATmega328 Pin8 –> GND
• ATmega328 Pin22 –> GND

To wire Reset button to your ATmega328, connect the following pins:

• ATmega328 Pin 1 –> Push Button Pin 1
• GND –> Push Button Pin 2
• Resistor 10K from ATmega Pin 1 to +5V
• Capacitor 100nF from ATmega Pin 1 to DTR (FTDI Pin)
