After using the Samytronix kit using visual block programming (S4A, mBlock), then it is time to take it to the next level. Start modifying projects and personalise it the way you want it. Add challenges and complexity to your projects. With the fundamental of coding that you have learnt, it is easier to start text based coding in C/C++ with the Arduino IDE. Connect more sensors and actuators such as ultrasonic, PIR, LCD, motors, relay, and many more options. Learn more about other open source hardware like the Arduino, Raspberry Pi and Leap motion, then combine them in your projects. Build anything you ever imagined, the possibility is endless. You have explored the world of coding and inventing! Happy making!
