Project Info - A working model of a laser communication system using 2 Arduino microcontrollers. One microcontroller with  a Laser is used at the transmitter and another microcontroller with LDR is used at the receiver. The input strings at the transmitter is converted to bits by the C code at the transmitter and these bits are fed into the Laser with a specified time interval for each bit to transmit. The transmitted pulses are received at the receiver and decoded back into the original string transmitted which can be viewed through the LCD display connected to receiver.
