For a robotics project i have to make an electrical circuit in which 5 light sensors need to light 5 corresponding LEDs.The LED must only turn on when the light sensors detect the infrared light from a laser pointer and afterwards must stay on permanently(assuming the battery is still running).We have a 9V battery that supplies power.We can use anything to make the circuit as long as its rather compact.We can use standard electrical parts like resistors transistors diodes etc.
Can someone please tell me of a way to do this or perhaps design a circuit to do this and tell me about it.
