The Dx-series parts have a 10-bit DAC which can generate a real analog voltage (note that this provides low current and can only be used as a voltage reference or control voltage, it cannot be used to power other devices). This generates voltages between 0 and the selected VREF (unlike...
See the Improved Digital I/O Reference.Serial (UART) SupportAll of the 0/1-Series parts have a single hardware serial port (UART or USART); the 2-Series parts have two. It works exactly like the one on official Arduino boards except that there is no auto-reset, unless you've wired ...
For us to be able to control the robot arm, it's really important that the servo motors are installed inknown'reference positions' and that we understand how they behave. This is a two step process ! Servo installation position procedure ...
Pins marked as Async Interrupt pins on the pinout chart (this is marked by an arrow where they meet the chip on those charts - pins 2 and 6 on all ports have this feature) can be used to wake from sleep on RISING and FALLING edge as well. The async pins can also react to inputs...
