Grove - Tilt Switch

pir

The Grove-Tilt Switch is the equivalent of a button, and is used as a digital input. Inside the tilt switch is a pair of balls that make contact with the pins when the case is upright. Tilt the case over and the balls don't touch, thus not making a connection. It is wired to the SIG line, NC is not used on this Grove.

caution
The platforms mentioned above as supported is/are an indication of the module's software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Getting Started​

Play With Arduino​

The SIG pin of the Grove - Tilt Switch output LOW normally. When the Tilt Switch is upright, a pair of balls inside the tilt switch will contact with the pins and the SIG pin will output HIGH.

The following sketch demonstrates a simple application of using the Tilt Switch and Grove - Button to control the led.

  • As the following picture indicates, the Tilt Switch is connected to digital port 5 of the Grove - Base Shield and the Grove-Button to digital port 7. The LED is connected to digital port 1. The hardware installation is as follows:

pir

  • Copy and paste code below to a new Arduino sketch.
void setup()
{
pinMode(1, OUTPUT);
pinMode(5, INPUT);
pinMode(7, INPUT);
}

void loop()
{

if (digitalRead(5)==HIGH)
{
digitalWrite(1, HIGH);
delay(100);
digitalWrite(1, LOW);
}

if (digitalRead(7)==HIGH)
{
digitalWrite(1, HIGH);
delay(200);
digitalWrite(1, LOW);
}

}
  • Upload the code.
  • Then the LED will light when you press the button or activate the tilt-switch. Have a try!

Play with Codecraft​

Hardware​

Step 1. Connect a Grove - Tilt Switch to port D5, then connect a Grove - Button and Grove - Red LED to port D7 and D2 of a Base Shield.

Step 2. Plug the Base Shield to your Seeeduino/Arduino.

Step 3. Link Seeeduino/Arduino to your PC via an USB cable.

Software​

Step 1. Open Codecraft, add Arduino support, and drag a main procedure to working area.

note
If this is your first time using Codecraft, see also [Guide for Codecraft using Arduino](https://wiki.seeedstudio.com/Guide_for_Codecraft_using_Arduino/).

Step 2. Drag blocks as picture below or open the cdc file which can be downloaded at the end of this page.

pir

Upload the program to your Arduino/Seeeduino.

tip
When the code finishes uploaded, tilt the tilt switch or press the button, the LED will goes on.

  • Step 2. Plug the Grove Base Hat into Raspberry.
  • Step 3. Connect the tilt switch to port 12 of the Base Hat.
  • Step 4. Connect the Raspberry Pi to PC through USB cable.

note
For step 3 you are able to connect the tilt switch to **any GPIO Port** but make sure you change the command with the corresponding port number.

Software​

note
 If you are using **Raspberry Pi with Raspberrypi OS >= Bullseye**, you have to use this command line **only with Python3**.
  • Step 1. Follow Setting Software to configure the development environment.
  • Step 2. Download the source file by cloning the grove.py library.
cd ~
git clone https://github.com/Seeed-Studio/grove.py

  • Step 3. Excute below commands to run the code.
cd grove.py/grove
python3 grove_tilt_switch.py 12

Following is the grove_tilt_switch.py code.


import time
from grove.gpio import GPIO


class GroveTiltSwitch(GPIO):
def __init__(self, pin):
super(GroveTiltSwitch, self).__init__(pin, GPIO.IN)
self._on_trigger = None
self._on_release = None

@property
def on_trigger(self):
return self._on_trigger

@on_trigger.setter
def on_trigger(self, callback):
if not callable(callback):
return

if self.on_event is None:
self.on_event = self._handle_event

self._on_trigger = callback

@property
def on_release(self):
return self._on_release

@on_release.setter
def on_release(self, callback):
if not callable(callback):
return

if self.on_event is None:
self.on_event = self._handle_event

self._on_release = callback

def _handle_event(self, pin, value):

if value:
if callable(self._on_trigger):
self._on_trigger()
else:
if callable(self._on_release):
self._on_release()

Grove = GroveTiltSwitch


def main():
import sys

if len(sys.argv) < 2:
print('Usage: {} pin'.format(sys.argv[0]))
sys.exit(1)

swicth = GroveTiltSwitch(int(sys.argv[1]))

def on_trigger():
print('Triggered')
def on_release():
print("Released.")

swicth.on_trigger = on_trigger
swicth.on_release = on_release

while True:
time.sleep(1)


if __name__ == '__main__':
main()


tip
If everything goes well, you will be able to see the following result when you touch the tilt switch

[email protected]:~/grove.py/grove $ python3 grove_tilt_switch.py 12

You can quit this program by simply press ++ctrl+c++.

Play With Raspberry Pi (with GrovePi_Plus)​

With Raspberry Pi​

note
 If you are using **Raspberry Pi with Raspberrypi OS >= Bullseye**, you have to use this command line **only with Python3**.

1.You should have a Raspberry Pi and a Grovepi or Grovepi+.

2.You should have completed configuring the development enviroment, otherwise follow here.

3.Connection

  • Plug Tilt_Switch into grovepi socket D3 by using a grove cable.

4.Navigate to the demos' directory:

       cd yourpath/GrovePi/Software/Python/
  • To see the code
    nano grovepi_tilt_switch.py   # "Ctrl+x" to exit #
    import time
import grovepi

# Connect the Grove Tilt Switch to digital port D3
# SIG,NC,VCC,GND
tilt_switch = 3

grovepi.pinMode(tilt_switch,"INPUT")

while True:
try:
print grovepi.digitalRead(tilt_switch)
time.sleep(.5)

except IOError:
print "Error"

5.Run the demo.

    sudo python grove_tilt_switch.py

6.Result: Put the sensor upright by one side, the SIG pin will output HIGH.
