Summary


That was fun, right? And a bit challenging, correct? Good! That's when you know you are learning. So let's just summarize what we achieved in this chapter. We first programmed a HC-SR04 Ultrasound sensor and used it to measure a distance which was then displayed on the Arduino UNO Serial Monitor. Next, we played around with the I2C LCD1602 screen, and then, we combined what we learned from the two sections into one project called the Digital Ruler (Scale). You successfully created a digital measuring tape, which made it compact and less cumbersome to use. But since it can measure between 0 to 2 meters, it can only be used indoors. Higher ranges can be achieved using better (and more expensive) sensors.

In the next chapter, we will learn about touch sensors, which will along with a powerful processing software allow us to convert finger gestures to text.
