The LCD connections are stated below
1|VSS| -> Arduino GND
2|VDD| -> Arduino +5v
3|VO | -> Arduino GND pin
4|RS | -> Arduino pin 12
5|RW | -> Arduino GND - pin can be conected to 11. But Ground was used here.
6|E | -> Arduino pin 10
7|D0 | -> Arduino - Not Connected
8|D1 | -> Arduino - Not Connected
9|D2 | -> Arduino - Not Connected
10|D3 | -> Arduino - Not Connected
11|D4 | -> Arduino pin 5
12|D5 | -> Arduino pin 4
13|D6 | -> Arduino pin 3
14|D7 | -> Arduino pin 2
15|A | -> Not Connected
16|K | -> Not Connected
Updated circuit diagram.
Capacitive proximity sensor requires 12V to operate.
The 1A measurement was made using a multimeter at the 9V output when it is not connected to the Arduino
