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.

- Drive a 2-phase bipolar stepper motor or two DC motors with the L298 dual H-Bridge chip, mounted on this handy breakout board along with all necessary peripherals!
- It is ideal for robotic applications and well suited for connection to a microcontroller requiring just a couple of control lines per motor. It can also be interfaced with simple manual switches, TTL logic gates, relays, etc.
