Single Color LED (use with mDesigner)

The Single Color LED is a light emitting diode (LED), which is capable of illuminating a single color. Red, green and yellow are the common colors. Support for this trinket is found in mDesigner.

Blocks

Set Pin

This block sets the voltage level on the selected pin either to high or low. In Arduino, this is know as a digital write (digitalWrite).

• When set to high, the Single Color LED turns on (illuminates).
• When set to low, the Single Color LED turns off (no illumination).

• Pin Number - the pin to configure the state of.
• State - set the pin to "high" or "low" state.

Examples Uses

Software Setup for Examples

• Setup your software for either Live Mode or Arduino Mode.

Hardware Setup for Examples [[]]

• Example 1: Turn off the Single Color LED connected to pin 6.

• Example 2: Turn on the Single Color LED connected to pin 6.

• Example 3: Turn on the Single Color LED connected to pin 6, wait 1 second, then turn off, wait another second, then loop repeatedly.

Set Pin PWM

This block sets the voltage level on the selected pin varying values. In Arduino, this is known as an analog write (analogWrite). Values between 0 and 255 will cause the Single Color LED to turn on at different levels.

• When set to 255, the Single Color LED is at maximum on.
• When set to 0, the Single COlor LED is off.
• When set to 127, the Single Color LED is half-way on.
• Other values between 0 and 255 will turn on the LED at appropriate brightness levels.

Note: Only pins which support "Analog Write" will work correctly with this block. *For Microduino / mCookie Core: Pins 3, 5, 6, 9, 10, and 11 *For Microduino / mCookie Core+, mCenter+: Pins 7, 8, 9, 10, 12, 13, 22, and 23

• Pin Number - the pin to configure the state of. Note: Only certain pins support this ability. See above for which pins has this ability in your hardware setup.
• Value - the value between 0 and 255 to set the pin to.

Examples Uses

Software Setup for Examples

• Setup your software for either Live Mode or Arduino Mode.

Hardware Setup for Examples [[]]

• Example 1: Turn off the Single Color LED connected to pin 6.
  (Note: Change the pin number to one that supports this block, see yellow box above)

• Example 2: Fully turn on the Single Color LED connected to pin 6.
  (Note: Change the pin number to one that supports this block, see yellow box above)

• Example 3: Turn the Single Color LED half way on (127 out of 255 ~= 0.5) connected to pin 6.
  (Note: Change the pin number to one that supports this block, see yellow box above)

• Example 4: Turn the Single Color LED connected to pin 6 full on (255), wait 1 second, then set half way on (127), wait another second, then loop repeatedly.
  (Note: Change the pin number to one that supports this block, see yellow box above)
