+{{:zheleznaja_chast:dmx_r_6s.jpg?300|}}
+The control signal from the DMX connector is fed to the **SN75176** buffer chip, and from it to the RX input of the Arduino microcontroller. After processing and decoding the signal (//if the address transmitted via the bus corresponds to the preset address of the microcontroller//) signals from the outputs of the microcontroller are fed to the transistor keys.
+The keys, in turn, control the brightness of the corresponding LED fixtures. If necessary, you can change the program of the microcontroller so that the DMX signal controls the keys in binary mode (**on/off**). It should be ensured that the current through each transistor does not exceed 0.5 amperes or set the output
+Transistors for radiators.
