the title is enough self explanatory ; )
i'd like to establish a communication between an IR led and its respective sensor using the RX and TX pins, and the serial transmission protocol as well (the one used to communicate with the pc). In this way i should be able to send and receive data just using Serial.write() and Serial.read(), shouldn't i? is this possible? if yes, which is the proper baud rate? what distance range can i cover in this way? is possible to converge the light into a point (like a laser, but less dangerous)?
do you think i'll need an expensive laser in order to send data to the sensor?
The results of shooting to be transmitted somewhere or between players only?
