In this project, I will be designing an alarm device that will be triggered by a touch. For this project you will be needing a human touch sensor (KY-036). Let me give you a glimpse of this project.
As you can see in the images above, the touch sensor has a pin, bent over the transistor, which will complete the circuit by a touch. The alarm will be set off when you touch the pin of the sensor, turning the LED red and activating the buzzer.
Schematic of KY-036:
Supplies
- Arduino Uno/ Nano
- USB cable (USB 2.0 Type A male to B male Cable)
- Solderless Breadboard
- Human Touch sensor module (KY-036)
- Two-colour LED module (KY-011)
- Active buzzer module (KY-012)
- 10cm male-to-male jumper wires (x5)
- 70 cm male-to-male jumper wires (x6)
Setup
For more information about the setup, please watch the YouTube video posted in the bottom of this page.
Connections
- Buzzer module - D3
- Green (KY-011) - D4
- Red (KY-011) - D5
- Digital Output (DO) of Human Touch sensor - D6
- VCC(+) of Human Touch sensor - 5V
- (-) of Human Touch sensor - GND (Ground)
