How Does LED Brightness Vary with Current? Help needed

Post by sjwatters4 »

My son is preparing his science fair project: How Does LED Brightness Vary with Current? although the Light-to-voltage converter part number TSL252R-LF is not available via Mouser Electronics nor Jameco as noted in the materials list.

Will the experiment work if we use ams 856-TSL257-LF from Mouser instead of TSL252R-LF?

Hi - yes, the project instructions have been updated to list the TSL257, available from both Digikey and Mouser:

Sorry about that!
