I have made loads of arduino projects. Its all fun and easy but as someone mentioned it has its limits. If you are new to programming its perfect. Done! But not on arduino . I'm doing my thesis report now. Its about 3-Phase Brushless DC Motor Control . I made the Technics go 16,33,45,78, ± (50%),more torque and backwards all in one.But there is more work to do with torque and speed control before I say "Success".
