Lux Meter Using VELM6040

Introduction: Lux Meter Using VELM6040

Part time tinker, Brute Force programmer. My codes are often big but are functional.

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

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.
