In the previous two chapters, you used the original ESP8266, which is ESP01 and the Arduino UNO to drive motors with a motor driver. You should have noticed that the ESP01 has only two general-purpose input/output (GPIO) pins. Using two GPIO pins, you can only drive a single motor through a motor driver. Therefore, for two motors, you will need four GPIO pins. As a solution, you used the Arduino UNO as a bridge between the ESP01 and motor driver. In the previous two projects, the ESP01 was used to provide all networking facilities through Wi-Fi and the Arduino UNO worked as the microcontroller.
In this chapter, you will learn the following topics:
- About the Feather HUZZAH ESP8266
- About the DC Motor + Stepper FeatherWing
- Assembling the Mini Round Robot Chassis Kit with Feather HUZZAH ESP8266 and DC Motor + Stepper FeatherWing
- Creating a Blynk app with a Joystick widget
- Writing an Arduino sketch to communicate with the Blynk...
