+MOC3043M:
+- led trigger current : 5mA
+- Input Forward Voltage : 1.25V
+
+So, (3.3V - 1.25V) / 5mA = 2.05V / 5mA = 410 Ω
+If we use 330Ω instead of 410Ω, we have : 2.05/330 = 6mA < 12mA.

+ESP12F:
+- GPIO max current : 12mA
+- Operating Voltage : 3.0~3.6
+- Operating Current Average value : 80mA
+- Power consumption (worst case) Tx802.11b, CCK 11Mbps, P OUT=+17dBm : 170mA
+- Peak Consumption: 500mA

+Total power consumption : 6mA * 5MOCs + 500mA =530mA
