4. O'rnatish va yig'ish bo'yicha ko'rsatmalar
O'rnatish bo'yicha umumiy maslahatlar:
- **Tools Required:** Soldering iron (<50 Watt), rosin core solder, wire cutters, wire strippers, Philips screwdriver.
- Be patient throughout the installation process.
- Avoid prolonged contact of the soldering iron with components (max 1.0 second) to prevent damage.
- Pay close attention to component polarity (positive and negative).
- Strictly avoid short circuits.
- Avval murakkab komponentlarni o'rnating.
- Ensure all components are in the correct direction and place.
- Wear anti-static gloves or wristbands when handling electronic components.
- Install LEDs according to specified rules; incorrect installation will prevent them from lighting.
- It is strongly recommended to read the entire manual before starting assembly.
Detailed Assembly Steps:
- **Step 1: Install 20Kohm Metal Film Resistors (R1, R3)**
Install two 20Kohm metal film resistors at positions R1 and R3 on the PCB. Identify the resistor value by its color code. - **Step 2: Install 470ohm Metal Film Resistors (R4, R5)**

The leads of the LED must be installed correctly. Incorrect installation will prevent the LED from lighting. Here are methods to identify polarity:- **Length:** The longer pin is the positive (anode) lead; the shorter pin is the negative (cathode) lead.
- **Internal Structure:** Look into the plastic case; the negative (cathode) side is typically thicker/bigger than the anode side.
- **Flat Edge:** The negative (cathode) lead is the pin nearest to the flat edge on the plastic case.
- **Test with 3V Battery/Multimeter:** Connect the LED to a 3V power supply (briefly, less than 0.5 seconds). The pin connected to the positive of the 3V supply that makes the LED light up is the positive (anode) lead.
- **PCB Markings:** The white mark '+' on the PCB indicates the positive (anode) connection.
