  2. Lüliti VDD VDD ~0,1-10 kΩ PIC ~0,1-10 kΩ

  3. Lüliti VDD PIC Kui kasutada Port B Weak Pull-uppi, pole välist takistit vajagi

  4. Lüliti VDD PIC Kui Port on Open-Drain (lahtine kollektor), peab väline takisti kindlasti olema

  5. Lüliti kontaktide värelemine VDD • Lugeda pordi seisu mitu korda • Kondekas PIC

  6. Lüliti kontaktide värelemine VDD • Lugeda pordi seisu mitu korda • Kondekas • R-S triger PIC
