Sounds doable, but keep in mind a few things. First, isolate the blender’s power so the microcontroller doesn’t fry. Use a separate relay or MOSFET to switch the motor, and control speed with PWM. Second, pick a sensor that can sense the whisk position—maybe a simple potentiometer or a hall effect sensor on the arm. And lastly, make sure you have a safety cut‑off: if something jams, the circuit should shut down quickly. If you set up a basic prototype with an Arduino and a few sensors, we can iterate on the control logic and get that auto‑whisking working. Let's sketch the circuit and list the parts, then we’ll tackle the firmware.
