Integration Tips for Arduino, Raspberry Pi, and Microcontrollers 🛠️

• Operate within the specified VDD = 3.0 V to 18 V range; when using Arduino (5 V) or Raspberry Pi (3.3 V), match logic levels to ensure reliable triggering.
• Use proper decoupling (e.g., 0.1 µF ceramic close to VDD/GND) to minimize supply noise at higher clock rates.
• When powering the CD4013 above your microcontroller I/O voltage, add appropriate level shifting or ensure inputs are never driven beyond VDD.
• Keep unused inputs at a defined logic level (pull‑up or pull‑down) to prevent floating inputs and excess current.
