Forums user lardot wrote in requesting assistance to operate the correct motor in their robotic hand project. Turns out the fault was not in the design or the wiring but simply selecting the correct COM port on their laptop to initiate upload to the Arduino – simple fix! But what’s really amazing is lardot got this far without even so much as a multimeter – proof that if you have an idea you can build it and if you persevere it will ultimately work! It’s a great looking robot hand and we look forward to seeing its completion and operation in the future. Read more here.
