hi guys,
i am currently doing a project!kindly requesting for help!!
i need a circuit to detect the laser beam from a laser pointer and then it gives the signal to a digital counter that displays counting in a 7 segment display!
i have the laser pointer circit!
i wan to know how to build the circuit that is going to be around 3meter away from my pointer. Everytime this circuit detects the laser the counter has to count up!
thanks in advance!!
