The hardware consists of

arduino nano

ssd1306 based i2c-128x32 oled

velm6040 sensor,

either

3 pushbuttons and optocoupler (817c) with 220 ohm resistor

or

2 push button and a toggle switch.

choose your flavor

Step 2: The Code

the code was wirtten in arduino ide

I've left a lot of comments in the code so that ,hopefully those who want to modify it, will find it easy to do so.
