The Digilent PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. Digilent Engineers designed this Pmod around the Texas Instruments ADC081S021 analog-to-digital converter.
The PmodALS utilizes a single ambient light sensor (ALS) for user input. The amount of light the ALS is exposed to determines the voltage level passed into the ADC, which converts it to 8-bits of data. A value of 0 indicates a low light level and a value of 255 indicates a high light level.
