On/Off: Neopixel (WS2812) RGB Strip with Raspberry Pi
Control the LEDs of a neopixel light strip. USE WITH CAUTION: This library uses the Hardware-PWM0 bus. Only GPIO pins 12 or 18 will work. If you use one of these pins for a NeoPixel strip, you can not use the other for Hardware-PWM control of another output or there will be conflicts that can cause the Mycodo Daemon to crash and the Pi to become unresponsive. If you need to control another PWM output like a servo, fan, or dimmable grow lights, you will need to use the Software-PWM by setting the Output PWM: Raspberry Pi GPIO and set the "Library" field to "Any Pin, <=40kHz". If you select the "Hardware Pin, <=30MHz" option, it will cause conflicts. This output is best used with Actions to control individual LED color and brightness.

| Calibration: a calibration can be performed to increase the accuracy of the pump. It's a good idea to clear the calibration before calibrating. First, remove all air from the line by pumping the fluid you would like to calibrate to through the pump hose. Next, press Dispense Amount and the pump will be instructed to dispense 10 ml (unless you changed the default value). Measure how much fluid was actually dispensed, enter this value in the Actual Volume Dispensed (ml) field, and press Calibrate to Dispensed Amount. Now any further pump volumes dispensed should be accurate. |
