The KY017 is a mercury tilt switch that allows you to detect the tilt of your object so that you can take the appropriate action. It is a nice low cost alternative to a 6 axis accelerometer. When strategically adjusted or situated, it can be very sensitive. The key to using this switch successfully is in understanding the two operational states.

The Keyes-039 or KY039 Heart rate monitor consists of two things, an Infrared LED, and an Infrared Phototransistor. The IR LED should come on whenever the sensor has power and stay on (because it is infrared, you won’t be able to see that it is on, but if you look through your cell phone camera you will). The IR photo transistor causes the voltage to change on a “sensor” wire, and this should be connected to one of the Arduino’s analog pins.

The Arduino Motor Shield is based on the L298, which is a dual full-bridge driver designed to drive inductive loads such as relays, solenoids, DC and stepping motors. It lets you drive two DC motors with your Arduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features.

L9110 chip is able to drive a single DC motor using two digital control inputs. One input is used to select the motor direction while the other is used to control the motor speed. Speed is controlled by using PWM Pulse Width Modulation. Motor drivers typically have what is called a truth table that determines the effect of its inputs.

The LilyPad Arduino consists of an ATmega328 with the Arduino bootloader and a minimum number of external components to keep it as small (and as simple) as possible. This board will run from 2V to 5V and offers large pin-out holes that make it easy to sew and connect. Each of these pins, with the exception of ( ) and (-), can control an attached input or output device (like a light, motor, or switch).

Introduction: The turbidity sensor detects water quality by measuring the levels of turbidity. It uses light to detect suspended particles in water by measuring the light transmittance and scattering rate, which changes with the amount of total suspended solids (TSS) in water. As the TTS increases, the liquid turbidity level increases. Turbidity sensors are used to measure water quality in rivers and streams, wastewater and effluent measurements, control instrumentation for settling ponds, sediment transport research and laboratory measurements.
