In this chapter, you built the hardware assembly for the Mini Round Robot with the Adafruit Feather HUZZAH ESP8266 and the DC Motor + Stepper FeatherWing. You also built a mobile app with Blynk and wrote the Arduino UNO sketch to control the robot through a Wi-Fi network.
As a simple improvement, you can add a slider widget to the Blynk app to control the speed of your robot. See how it turns to the left or right at its maximum speed!
In Chapter 5, Line-Following Zumo Robot, you will build a line following robot using the Zumo Chassis Kit with Adafruit Feather HUZZAH ESP8266.
