Step 1: Shoping for the Parts Used.
- Arduino board(any)
- Alcohol sensor
- led light(optional for indication)
- Nokia 5110 lcd
Step 2: Make the Connection As in Pic and in Schematics
connect the the Nokia LCD pin as follows
SCK - Pin 8
MOSI - Pin 9 //
DC - Pin 10 //
RST - Pin 11 //
CS - Pin 12
and connect the sensor out pin in pin 7 of Arduino and connect the relay and buzzer pin to Arduino pin 13
Make the connections stated above and as described in schematics pic above.
