The Adafruit 16-Channel 12-bit PWM/Servo Driver will drive up to 16 servos over I2C with only 2 pins.

Driving servo motors with the Arduino Servo library is pretty easy, but each one consumes a precious pin - not to mention some Arduino processing power. NI Multisim andNI Ultiboard provide an integrated platform to design, simulate and lay out a complete Printed Circuit Board (PCB).The simulated frequency response will appear. Click the Run button in the Multisim toolbar or F5.In the Instrument control Panel > Device select > Simulate NI myDAQ.Double click on the Bode Analyser icon, highlighted with a red circle below, on the myDAQ symbol.Right Click on the function generator icon on the myDAC symbol and select NI myDAQ instrument enabled in simulation.Simulating the frequency response of the circuit In this case we wish to measure with respect to ground so we connect AI_0- and AI_0- to analogue ground (AGND) Remember all voltages are measured across two points.AI_1+ is used to measure the output voltage across the Capacitor.

AI_0+ is used to measure the input voltage.

Analogue ground (AGND) is attached to the ground reference point of your circuit i.e.

You must ensure the following conditions are met: To wire components hover over point where you wish to connect to, left click, then move to the location for the end of the wire and left click to finish. To place the components, resistor and capacitor, either right click and select place component, or click the place basic button in the toolbar.

Select File > New and then NI myDAQ design in the New design window shown below.

Or if you don’t have a Resistor or LED to hand, use the Digital Reader and wire one of the DIO to 5V. Or use the Digital Writer with an LED connected between DIO7 and DGND. Note you need to press the run arrow to start making a measurement.

You can use this to directly test the operation of the myDAQ by opening the Digital Multimeter, attaching the probes to the base of the unit and measuring the resistance of a resistor. If installed correctly the NI ELVISmx instrument launcher will open when you plug the myDAQ into the USB port. Note this software only works on windows, if you have Mac, however, then all is not lost you simply need to use bootcamp to install windows 8.1 first and then install MultiSim and ELVISmx. This guide assumes that you have first installed NI MultiSim 13 and then installed NI ELVISmx 14.0 driver for the NI myDAQ.
