**Steps:**
1. **Preparing electronic components:**
- Purchase an electronic components, Or it can be found in scrap
2. **Read the Manual:**
- Circuit diagram.
3. **Assemble the Components:**
- Use the soldering iron to carefully solder the components onto the provided circuit board following the instructions in the manual. Be sure to follow safety precautions when using the soldering iron.
4. **Connect the Antenna:**
- Connect the antenna to the designated antenna input on the circuit board. The length of the antenna may affect reception, so you can experiment with different lengths.
5. **Power Supply:**
- Connect the power source (battery or power supply) to the circuit. Make sure to observe polarity and voltage requirements.
6. **Testing:**
- Turn on the FM receiver and tune it to a known FM station. Adjust the antenna length for better reception.
7. **Enclosure (Optional):**
- If desired, place the circuit in an enclosure to protect it and make it more portable.
Remember that building an FM radio receiver is an educational project, and the performance may vary. If you're new to electronics, consider seeking guidance from someone with experience, and always follow safety precautions when working with electronic components. Additionally, be aware of local regulations regarding the use of radio equipment.
