Servo

Servos have integrated gears and a shaft that can be precisely controlled. Standard servos allow the shaft to be positioned at various angles, usually between 0 and 180 degrees. Continuous rotation servos allow the rotation of the shaft to be set to various speeds.

Set Position in Degrees with Delay

Writes a value to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft (in degrees), moving the shaft to that orientation. On a continuous rotation servo, this will set the speed of the servo (with 0 being full-speed in one direction, 180 being full speed in the other, and a value near 90 being no movement). A configurable delay time is added after calling the servo to move to allow to the requested angle.

  • Servo Pin # - The pin number that the servo is connected to.
  • Degree (0~180) - The angle to move the servo shaft to.
  • Delay (ms) - A delay in milliseconds after requesting the servo to move. This allows the servo physically move the servo shaft to the request angle.

Set Position in Microseconds (PWM)

Writes a value in microseconds (uS) to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft. On standard servos a parameter value of 1000 is fully counter-clockwise, 2000 is fully clockwise, and 1500 is in the middle.

  • Servo Pin # - The pin number that the servo is connected to.
  • Microseconds - Set the direct PWM value (instead of an angle) that is sent to the Servo.

Read Position

Returns the current angle of the servo (the value passed to the last call to Set Position in Degrees).

  • Servo Pin # - The pin number that the servo is connected to.

Tone

Output Tone with Frequency

Without Duration

Generates a square wave of the specified frequency (and 50% duty cycle) on a pin. A duration can be specified, otherwise the wave continues until a call to Stop Output Tone. The pin can be connected to a piezo buzzer or other speaker to play tone.

  • Tone Pin # - The pin number that has the attached piezo buzzer or speaker.
  • Frequency - The frequency of the tone in hertz to generate.

Note: Stop Output Tone needs to be called to stop tone generation.

With Duration

Generates a square wave of the specified frequency (and 50% duty cycle) on a pin. A duration can be specified, otherwise the wave continues until the duration time completes. The pin can be connected to a piezo buzzer or other speaker to play tone.

  • Tone Pin # - The pin number that has the attached piezo buzzer or speaker.
  • Frequency - The frequency of the tone in hertz to generate.
  • Duration (ms) - The time in milliseconds to output the tone.

Stop Output Tone

Stops the generation of a square wave triggered by Output Tone with Frequency Without Duration. Has no effect if no tone is being generated.

Setup

Setup the LCD display for use. This block is required to be called to initialize the LCD and configure.

Using Hardware I2C (Default)

  • LCD Type - The type of LCD connected -- LCM1602 or LCM2004.
  • LCD Name - Variable name for the LCD. Any name can be chosen. Used to reference in other blocks.
  • Address - I2C address of the LCD module connected. Usually, included in the datasheet or document that is supplied with the module. Or a simple Google search on the LCD module number will yield the I2C address. Or use an I2C scanner to detect the address.

Using Software I2C (Alternative)

  • LCD Type - The type of LCD connected -- LCM1602 or LCM2004.
  • LCD Name - Variable name for the LCD. Any name can be chosen. Used to reference in other blocks.
  • Address - I2C address of the LCD module connected. Usually, included in the datasheet or document that is supplied with the module. Or a simple Google search on the LCD module number will yield the I2C address. Or use an I2C scanner to detect the address.
  • SCL Pin # & SDA Pin # - SCL & SDA pin numbers to use with Software I2C. Read more here about software I2C: http://playground.arduino.cc/Main/SoftwareI2CLibrary

Print String

Display string on the LCD module.

Line 1 / Line 2

  • LCD Name - The name of the variable of the LCD as defined in the setup (see above).
  • Line 1 - String to display on the first line of the LCD screen.
  • Line 2 - String to display on the second line of the LCD screen.

Row / Column

  • LCD Name - The name of the variable of the LCD as defined in the setup (see above).
  • Row - Row number to where the start of the String will be printed.
  • Column - Column number to where the start of the String will be printed.
  • String - Text that will be display starting at the Row and Column.

Commands

Performs a command on the LCD.

  • LCD Name - The variable name of the LCD which will be acted upon. Variable name is set during the setup (see above).
  • Action - Various action to perform on the LCD.
    • On - Turns on the LCD screen.
    • Off - Turns off the LCD screen.
    • Cursor - Enables the cursor (under scroll) on the selected row and column on the display.
    • noCursor - Disables the cursor (under scroll) the display.
    • Blink - Enables character blinking on the selected row and column.
    • noBlink - Disables character blinking on the selected row and column.

Stepper Motor

Setup

  • 2 Pin
  • 4 Pin
