Goal : Send data from a single sensor to a program on a personal computer.
Serial monitor results using Serial.write() in Arduino :
ASCII representation of the byte using CoolTerm :
Hexadecimal representation using CoolTerm :
Graph of sensor values in processing :
GOAL : control a servomotor’s position using the value returned from an analog sensor.
What I ended up doing for my Stupid Pet Trick was completely different from my initial idea.
From the 2 ideas that I had I started on the camera idea and actually got it up and running. How it worked ; a motion sensor triggered a camera to take a photo. I was pretty happy that [...]
I have 2 ideas for my stupid pet trick.
1. CAMERA TRIGGERED BY SENSOR IN HAT
I would like to create a device that takes a photograph using a digital camera after a physical interaction triggers it. I would like the camera to be triggers once someone puts on a specific hat, with a sensor in [...]
Goal : Practicing basic electronic principles by trying them in action. Measuring voltage, amperage, and resistance using a multimeter.
STEP 6 : Building a basic LED circuit using an external power source and a voltage regulator. The voltage regulator converted the 12V input from the power source to 5V transmitted to the circuit.
VOLTAGE CALCULATION USING METER :
Power [...]
My fantasy device would solve the problem of lost remotes. A transmitter (infrared possibly) would be placed on the back of each remote and that would be detected using a cellphone camera and mobile app.
Below are all of the sensors I encountered during the walk from my apartment to ITP. I never realized that even before I left my apartment building I had interacted/encountered at least 4 sensors: elevator call button, elevator door sensor, floor call button, emergency light/exit sign.
Goal : to connect a variable resistor to a microcontroller and read it as an analog input.
SETUP
Potentiometer in action :
Here is a similar setup with a photocell.
For our first Physical Computing Assignment we had to program 2 LED lights using the Arduino micro controller and software. The goal is to have a red LED on when the micro controller is connected to a power supply and have it turn off if the switch is pressed, simultaneously turning another green LED on.
It took a [...]
