Finished Level Crossing, looks and operates very nicely (should have made the vertical pole smaller in diameter)Firstly worked out positioning of LED’s soldered shorter legs together (Check arduino sketch for either + or -)Using a breadboard, sensors and LED’s organized ArduinoCodeConstruct brass pole, note filed notch for wire accessWires brought out and top piece notched for wire access
I used old cat 5 cable wire for fine wiresI used large pop rivets cut off and drilled out for covers around lightsI soldered the LED wire that was joined to the brass pipe and passed the other 2 wires through pipe to solder the Other LED legShort leg soldered to brass pipe. Note white heat shrink to protect other LED leg touching brass pipe.Wires soldered and excess pushed back into brass pipeTop brass section carefully soldered into positionPop rivets painted black and glued in position. Everything paintedNice little shed to hid optical sensor used to turn on crossing lights
