Temperature in Morse Code

the detection of a loud sound from the sound sensor trips a temperature reading from the DHT11, and its binary value is sounded out by the buzzer (long beep = 1, short beep = 0)

Distance Displayed with 8 LEDs

one UNO transmits the distance read by a PING sensor to another, which displays the distance as a binary value by controlling 8 LEDs with port manipulation (on = 1, off = 0)
