Using dfrobot Romeo bluno for motor control experiment

dfrobot wheel diameter = 42.5mm

if RPM is 200 and time lapse is 15 sec, the robot should have tranverse

1/4 x 200 = 50 revolutions 

and the distance covered is 50 x pi x 42.5 = 6677mm.

Let's program this.

ESP8266 connection esp. pull-up resistor

ESP8266 V3 setup

based on http://www.esp8266.com/viewtopic.php?f=13&t=475#

CH_PD          Pull-up
GPIO16/RST     Pull-up
GPIO15         Pull-down
GPIO2          Pull-up
GPIO0          Pull-up for normal or pull-down for bootloader mode.

Pull-up = resistor to VCC.
Pull-down = resistor to GND.

Its possible to wire GPIO directly but then its hard to use them in future if needed. My resistors is 10k right now.
