I am very new to robotics but I was wondering if it is possible to get a sensor to detect a camera flash, then have that trigger a display to display a word or code? If so, what parts would I need, and how difficult would this be to set up? Thanks!
Hi,
Maybe an LDR like this Linker Light Sensor for pcDuino/Arduino or the Gravity Ambient Light Sensor would work but will need to be tested as camera flashes have an average duration of 1ms and typical response time of LDRs is 20-40ms so might be too slow.
You can take a look at this forum post : forum.arduino.cc/index.php?topic=369972.0
Photodiode based sensor might be a better fit. You can search for " Photodiode Light Sensor"
