I'm following the pace of the book, so I reached this paragraph "Recommended setup for programming ESP8266" where you summarize the parts list; you mentioned "Resistors – Some 10K, some 20K, some 330Ohm – A handful – $1.00". What power do you recommend for these resistors?
0.5 W, 1W, 2W, 3W?
0.125 1/8 watt at most. This is a 3.3 volt device with a maximum of 12ma on each GPIO. The 3mm and 5mm LED's on Ebay take 20ma to drive to full brightness. Using a LED calculator and a white LED (1.8V drop) a 125 Ohm resistor would pass 12ma at 0.0216 watts, 12ma is the max you would want to drive the IO PIN, 130 ohm is the closest value. 1/4 watt 157 values https://goo.gl/RnnPc5 or 1/8 watt less values https://goo.gl/Pv746H bottom of page
