Please note: RSVPing on meetup or facebook does not guarantee you a spot in the workshop. Tickets must be purchased in advance.

Sensors and actuators are used in virtually all the technologies that surround us from smartphones to devices in our cars, to appliances in our offices and homes.
Sensors are devices that capture physical properties such as temperature, pressure, humidity, location, light intensity, resistance, force, gravity, weight, etc. and convert them into digital inputs for the Arduino.
Actuators are devices that do the opposite: they take digital signals from the Arduino and convert them into light, sound, motion, display readings and other outputs that change the physical environment.

Come to the workshop if:
• You want to gain hands-on experience interfacing the Arduino with commonly-used sensors and actuators,
• You want to acquire a key building block in learning how to convert your projects into fully interactive creations
• You are already working on a project with sensors and actuators and just need a bit of extra knowledge and/or assistance to proceed
• You plan to attend upcoming workshops in this series where we learn to build an interface the Arduino with interactive smartphone apps

Agenda:
• Introductions
• Sensor and actuator: devices most commonly used and how to select them
• Interfacing devices with the Arduino (analog and digital GPIOs, Serial, I2C, SPI, other)
• Selecting sensor and actuator libraries to speed up prototyping
• Using serial monitor/terminals and Processing to visualize sensor data
• Hands-on project: choose one or multiple sensors to control actuators

Example demos and hands-on projects:
• Visualizing a 9-axis accelerometer, gyroscope, magnitometer with Processing
• Controlling a 12V-powered solenoid via a relay
• Animating a neopixel light strip or ring using a potentiometer
• Controlling a servo motor or a stepper motor using a capacitive sensing strip
• Using temperature to control a computer fan
• And many more. The only limits are your imagination and available technologies

Materials:
• Your favorite Arduino board
• Your favorite sensor and actuator devices
• Breadboard
• Hookup wires
• Arduino USB cable
• Personal computer with Arduino IDE installed
• Optional: install Processing stable release: https://processing.org/download/
• Note: instructor will have Arduino Uno boards and device samples to borrow
