    Crowtail Welcome to the world of Crowtail! Crowtail is a modulated, ready-to-use toolset, it takes a building block approach to assemble electronics. It simplifies and condenses the learning process significantly. In our Crowtail warehouse, there are over 150 Crowtail modules and Crowtail shields! The Crowtail products are basic-functional modules that consist of a Base Shield and various modules with standardized connectors, each Crowtail module has its specific functions, such as light sensing and temperature sensing.

  • Page 10: Lesson 3 - Hall Speed Test

    Code overview 1. Macro definitions of PIR motion sensor pin, LED pin and buzzer pin. 2. Declare a variable to store the state of the collision sensor. 3. Setup led and buzzer as output. 4. Read the state of the collision sensor and store it to the variable collisionState. 5.
  • Page 11 The output of the continuous-time switch Hall sensor output logic low(turns on) when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it output logic high( turn off) when the magnetic field disappears. The Hall sensor is a very practical electronic module. It can be applied in many aspects, such as measuring displacement, measuring speed and so on.

  • Page 12: Lesson 4 - Motor Control

    Code usage Constant: const int taketime = 5000; 'const' is the abbreviation of constants. If you use this to define variables, the variables are marked as “read-only”, that is, they cannot be changed during the program. Constants are great for declaring pin number variables that will not change throughout the program.
  • Page 13 Our Crowtail-Motor Base Shield includes 2 motor interfaces, which can drive two motors at the same time! Of course, a 4-wire stepper motor can also be driven. After inserting the Crowtail-Motor Base Shield into Arduino/Crowduino, the specific method of controlling the motor is as follows: In this course, we will use the Crowtail-Motor Base Shield motor interface to control two TT motors simultaneously.
  • Page 14 Be careful not to connect the motor to the interval interface, such as OUT1 and OUT3, otherwise, the motor will not work properly. The complete connection is as follows. Open the P04_Motor_Control with Arduino IDE and upload it. Note: Because the motor consumes more power, after uploading the code, you need to provide additional power for the Crowtail-Motor Base Shield (usually connect 9V power supply for the power input port of the motor base shield) and then turn on the onboard power switch(you don’t have to power Crowduino/Arduino, because the motor base shield will share the power with Crowduino/Arduino).
