Anyone into IoT/Hardware Hacking or IoT/Hardware Hacking tools development?

Hi , I am passionate cyber security researcher and more interested in IoT and Hardware pen-testing/hacking. Currently am in the phase of learning hacking tools development with arduino and iot development boards. It could be a great help if you share relevant projects, notes, lectures or any other stuff that can help me here. Thanks in advance.
