Summary
In this chapter, you learned to build a two-wheeled drive mini round robot with a caster ball. While doing this, you understood how to integrate ESP8266 ESP01 and Arduino UNO to control DC motors through a dual H-bridge motor driver. Then, you built a mobile app with Blynk and used a few Arduino libraries to build a complete sketch. Finally, you uploaded the sketch to the Arduino board.
In Chapter 3, Using Encoders, you will learn how to add wheel encoders to the Mini Round Robot and read values for average speed and distance traveled using a Blynk app.
