I would like to place a color sensor in front of a tv screen and whenever the picture become with more of a red color the sensor will create a rapid movement of a motor.
Is the above possible?
how much precise a color sensor can be of detection a specific color?
what sensor are you recommending for that? anything else I should look into?
Yes it is possible
Type this into Google; light sensor red wavelength
Focus on this. Code and test with serial print. When working open new sketch and start working on making your motor turn with serial input. Encapsulate in functions.
Join sketches in a new sketch
That is just a photo resistor. It cannot differentiate color. I've used RGB Color Sensor with IR filter and White LED - TCS34725 : ID 1334 : $7.95 : Adafruit Industries, Unique & fun DIY electronics and kits in a project before. It is plenty accurate to determine if something is "red" as you define it in your code.
Thanks for that.
what about the AD8232 ECG module? How complicated is to receive the analog data of them into arduino?
same question for this GSR sensor
Can I power both from the arduino itself? or day need an external power supply such when using a motor?
The first link is dead, but the second one says it draws 1mA, which is plenty low enough to power from an arduino.
