3. Design Considerations for Your Electronics

4. Design Considerations for Your Electronics
Consider sensor placement requirements
Consider accessibility of electronics
Consider your overall design and the operating environment

5. Extending Capabilities with Shields and Devices
Why shields?
Shield and device options
Options for interfacing with shields and devices

6. Sensor Types and Inputs
nearly unlimited selection
If you want it you can probably find it
Sensor connections – output and communication
Analog
PWM
Serial
I2C
USB

7. Motor Types and Motor Driver Shields
Common types of motors include
Servo
Standard DC motors and gearmotors
Stepper motors
Motor driver shields
Enable use of large, high power motors
Separate power supply and circuit
Lots of options for different motor types
Options for I2C, Serial, USB
Some include an Arduino library for easy programming

8. Distance Sensors Choosing a range/distance sensor
Hardware interface and configuration
Device sensitivity - converting sensor readings into distances

9. Coding for the ultrasonic rangefinder

10. Controlling Gearmotor Speed and Direction

11. Controlling Gearmotor Speed and Direction
Speed is proportional to the input voltage for a DC gearmotor
Direction is dependent on the direction of current flow
Motor driver shields and libraries

12. Controlling a DC gearmotor

13. Review
We discussed the available sensor and motor types that you can include in your projects.
We investigated rangefinder devices, how to choose one that fits your particular project, and how to take distance readings from an ultrasonic rangefinder.
We discussed motor driver shields and showed you how to control a gearmotor.
