When designing an electronic circuit, a set of basic elements and equipment must be available. Here is a list of tools and items you may need:
Basic elements:
1. **Resistors**: To determine current and control voltage.
2. **Capacitors**: To store energy and mitigate changes in voltage.
3. **Coils**: To store energy in a magnetic field.
4. **Transistors**: To amplify and switch signals.
5. **Diodes**: To allow current to pass in one direction only.
6. **Integrated Circuits (ICs)**: To assemble complex functions into a small package.
7. **Connectors and Wires**: To connect components together.
Tools and equipment:
1. **Breadboard**: To test designs without soldering.
2. **Printed Circuit Boards (PCBs)**: For final assembly of the circuit.
3. **Soldering iron**: To install components on printed circuit boards.
4. **Welding wire**: For fixed electrical connections.
5. **Wire shears**: To cut wires as needed.
6. **Multimeter**: To measure voltage, current, and resistance.
7. **Signal Generator**: To generate test signals.
8. **Oscilloscope**: To monitor electrical signals.
9. **Stable power supply**: To provide stable current to the circuit during testing.
10. **Circuit design programs**: such as Eagle or KiCad for designing printed circuits.
Helping tools:
1. **Precision pliers**: For handling small components and wires.
2. **Magnifying glass**: For inspecting welds and small components.
3. **Thermal insulator**: To protect sensitive components from heat during welding.
4. **Cleaning tools**: Such as a brush and acetone to clean the boards after welding.
