SENSORS AND SENSING
1.12.2022 water sensor https://lastminuteengineers.com/water-level-sensor-arduino-tutorial/
The water sensor is used to detect the presence of water and is typically used to monitor water levels, detect the presence of water or leaks in spaces that need to be kept dry or detect rain fall. The water sensor is essentially a variable resistor that has more or less resistance depending on the amount of water it comes in contact with. It works very well at detecting the presence of water but the jump to the maximum range very quickly when more than a few drops of water are applied.
To connect the Arduino, water sensor and three LED's to indicate the amount of water present I followed the circuit diagram and code here: https://create.arduino.cc/projecthub/123lYT/simple-water-level-sensor-with-led-ebf3f7
In this example the sensor is being used as a rain indicator, so three states were defined: Dry Weather, Average rain and Heavy rain. Depending on the level of water present one of three LED lights would turn on and a corresponding message would be printed in the Arduino console.

// read the input on analog pin 0:
int value = analogRead(A0);
Serial.println (value );
if (value > 500) {
Serial.println("Very heavy Rain");
digitalWrite (blue,LOW);
digitalWrite(red,HIGH);
digitalWrite(white,HIGH);}
else if ((value > 100) && (value <= 500)) {
Serial.println("AVERAGE Rain");
digitalWrite (red,LOW);
digitalWrite (blue,HIGH);
}
else{
Serial.println("Dry Weather");
digitalWrite (white,LOW);
digitalWrite (red,HIGH);
digitalWrite (blue,HIGH);
delay(100);
}

Learning Ritual
I have committed to creating one ritual or action per week from now for the duration of the semester. I begin the practice of ritual making from an inexperienced and inhibited place. Making rituals and talking about spirituality makes me uncomfortable, but this is also exciting. I feel clumsy and out of place and so somehow that means this is the right path. To begin this journey I am learning from Jane Batten and reading her book Power From Within: A feminist guide to ritual-making. She gives step be step instructions for crafting your own rituals including how to plan and structure a ritual, examples for each stage of the ritual and tips around specific ceremonies. Batten also touches on my thinking around ritual - the fears and the reasons to pursue a ritual practice. She talks about the general disapproval to terms like 'ritual', 'spirituality' and 'witch', the feeling that ritual is not real and is more a personal indulgence and the fear that ritual might actually unleash a power within us, all of which touch on the resistance I feel to inhabiting a more spiritual way of being. However she notes "it is no use working to change structures if we do not also change ourselves, a key point that resonates with my reasons for beginning this process. I also identified with her critique of white New Zealander's as "living in a spiritually bereft culture" calling for us to not appropriate the spirituality of the Maori people but to "address our own spiritual needs, evolving a sense of ritual that is relevant for ourselves, right here and now". This is the departure point for this project.
20.12.2022 Deep Listening Practice
Deep Listening is a process and a tool to aid in conscious listening. Developed by musician Pauline Oliveros this is a practice to expand our perception of sounds out into the environments around us, out into the 'space/time continuum of sound' and through this expansion to be connected with the environment. Deep listening practice consists of energy work, body work, breathe exercises, vocalising, listening and dream work. Working from the book Deep Listening: a composers sound practice by Oliveros I am exploring Deep Listening as a technique to develop connection with rivers. This is is also linking with work I am doing around soundscapes and recording the sounds of the river as a way of listening- with, being-with and making-with the river.
