Exercise 3: Switches

Introduction

Line: 36 to 36
 The ESP32 has an interface to read capacitive touch sensors (see https://docs.micropython.org/en/latest/esp32/quickref.html?highlight=touchpad). Write a program to read out the touch sensor and to find out if a wire is touched or not. You may use this again to switch on and off LEDs.

Exercise 6:

Changed:
<
<		Write a program scanning the PIR sensor, indicating if a person is close. The PIR sensor, just like the push button, uses a single GPIO line as input. The boards allow choosing which GPIO to use, and I selected D4 = GPIO 16
