Page 5: Introduction
Introduction On-board the KY-036 touch sensor module there are the MPSA13 Darlington transistor, a few resistors, two LEDs, a potentiometer and an LM393 analog voltage comparator chip. The MPSA13 Darlington transistor is used as the touch sensor. Transistors have three legs one for the base, one for the emitter and one for the collector. -
Page 6: Specifications
With some adjustment of the potentiometer, when the analog voltage is read via an analog to digital converter (ADC for short), the digital value of the voltage is around 1023. That is the state when the KY-036 sensor is not touched. -
Page 7: The Pinout
The pinout The KY-036 touch sensor module has four pins. The pinout diagram is shown on the following image: - 5 -... -
Page 8: How To Set-Up Arduino Ide
How to set-up Arduino IDE If the Arduino IDE is not installed, follow the link and download the installation file for the operating system of choice. For Windows users, double click on the downloaded .exe file and follow the instructions in the installation window. - 6 -... - Page 9 For Linux users, download a file with the extension .tar.xz, which has to be extracted. When it is extracted, go to the extracted directory and open the terminal in that directory. Two .sh scripts have to be executed, the first called arduino-linux-setup.sh and the second called install.sh.
- Page 10 Almost all operating systems come with a text editor preinstalled (for example, Windows comes with Notepad, Linux Ubuntu comes with Gedit, Linux Raspbian comes with Leafpad, etc.). All of these text editors are perfectly fine for the purpose of the eBook. Next thing is to check if your PC can detect an Atmega328p board.
- Page 11 If the Arduino IDE is used on Windows, port names are as follows: For Linux users, for example port name is /dev/ttyUSBx, where x represents integer number between 0 and 9. - 9 -...

Page 12: How To Set-Up The Raspberry Pi And Python
How to set-up the Raspberry Pi and Python For the Raspberry Pi, first the operating system has to be installed, then everything has to be set-up so that it can be used in the Headless mode. The Headless mode enables remote connection to the Raspberry Pi, without the need for a PC screen Monitor, mouse or keyboard. -
Page 13: Connecting The Module With Atmega328P
Connect the KY-036 module with the Atmega328p as shown on the following connection diagram: KY-036 pin > Mc pin > Red wire > Black wire > Green wire > Blue wire With this set-up both the analog and digital pins of the KY-036 module are used. - 11 -... -

Page 17: Python Script
Python script import RPi.GPIO GPIO from time import sleep GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) # Pin setup for the module Digital_PIN GPIO.setup(Digital_PIN, GPIO.IN) print('[Press CTRL + C to end the script!]') try: # Main program loop while True: GPIO.input(Digital_PIN): print('Touch detected') else: print('No touch') sleep(1) # Wait for a second... - Page 18 Save the script by the name touch.py. To run the script open terminal in the directory where the script is saved and run the following command: python3 touch.py The result should look like the output on the following image: To end the script press CTRL + C on the keyboard. Now it is the time to learn and make your own projects.
