Here is what I am looking for:
Utilizing the following items:
http://www.makeblock.com/electronic-robot-kit-series-STEM/me-auriga ,
http://www.makeblock.com/me-line-follower ,
http://www.makeblock.com/me-bluetooth-module-dual-mode
OR
http://www.makeblock.com/bluetooth-module-for-mbot ,
Two each http://www.makeblock.com/me-7-segment-serial-display-red or http://www.makeblock.com/me-tft-lcd-screen-2-2-inch OR http://www.makeblock.com/lcd-control-panel
18V DC motor 1.5A Max
Two Switches http://www.makeblock.com/me-micro-switch-a
and or http://www.makeblock.com/me-micro-switch-b
One each http://www.makeblock.com/me-dual-dc-motor-driver
to drive a MOSFET to drive the 18V DC motor 1.5A Max
12" circumference wheel driven by the 18V DC motor 1.5A Max
Utilizing the above, and upon activation of both momentary switches, the display(s) will clear and the motor will utilize PWM to gradually* rotate the motor to full speed.
When switch 1 is released, the RPM of the motor as detected by the ir detector
of the line follower and detector (included in the kit) against a reflective
surface on the 12" circumference wheel driven by the 18V DC motor 1.5A Max
will display on line one or one of the display(s) as a RPM value and the motor
will continue to speed up. This value will remain on line one or one of of the
display (s).
When switch 2 is released, the RPM of the motor as detected
by the ir detector of the line follower against the same reflective surface on
the 12" circumference wheel driven by the 18V DC motor 1.5A Max will
display on line TWO or the second display(s) as a RPM value and the motor will stop rotating. This value will remain on both
lines or both display(s).
Both values will remain on the display(s) until Both switches are depressed.
*Note: the interval between the steps of the motor may need to be changed and
the “starting” of the motor may need a momentary full voltage to
overcome inertia and get the motor spinning. The start point of the motor may
have to be changed as too low PWM on the motor may not get it to spin at all.
Additionally, and For example, at 500 ms between acceleration steps, it would
take 2 1/4 minutes to get to full speed from zero. I won’t know what that start
point would be.
Being able to view and adjust values on the Makeblock Application.
