This project reads the values of velm6040 sensor,convert them in lux,and display it in 3 different ways,as described above in image.
Senstivity of the sensor can be toggled with the push buttons
there are also pushbuttons for "freezing" the display and toggle the led,on-off
Step 1: Hardware
The hardware consists of
ssd1306 based i2c-128x32 oled
3 pushbuttons and optocoupler (817c) with 220 ohm resistor
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.
