Review on KEYESTUDIO Arduino Electronic Robotics Bluetooth by Allen Wagner

Great product. It comes with the tools you need to assemble everything. The wiki has step-by-step instructions and instead of just copying/pasting the code to make it work, it's divided into segments that describe how to test and troubleshoot each step. Example: how to use a stepper motor, how to connect two stepper motors. How to control with a joystick. etc. etc. This allows you to understand each process as you build it. Great learning experience
