OCTAL PERIPHERAL DRIVER ARRAY ARDUINO SHIELD
Octal peripheral driver array chip ULN2803 is used too boost up the voltage and current on 8 arduino outputs. Suitable for switching relays and other devices that require higher current.

Driver ULN2803 limit is 500 mA per channel. I used only the non PWM arduino pins - skipped the ones that can be used for PWM since for the funcion this shield is made for (ON/OFF), it is not required. Added the LEDs so that you can always have a vidual information in what state the output is. |
