In this chapter, you learned about the building block of circuits. You now know about voltage, current, resistance, and the relationship between them. You learned about various combinations of resistors and capacitors and how they collectively work in circuits. You also learned about the physics behind sensors, you now know what process to follow to solve any problem in the world, and most importantly, you built your own sensor!
In the next chapter, you are going to learn everything about Arduino, how to write code, how to tinker with examples and attach sensors to Arduino. I am super excited. Are you?
