Click upload button or select Upload from Sketch menu.

Board installation

Disconnect USB to UART converter from ESP board.
Remove jumper wire between D0 and Ground pins.
Switch SW1 to ON.
Remove jumper wires from Motor Shield board.
Install ESP board atop of Motor Shield board.
Connect jumper wires to Arduino side connector between D5 and D13 pins, and between D10 and D12 pins if you use Arduino UNO DCC++, or between D2 and D13 pins for Arduino MEGA DCC++.
