Siren Alarm PCB Board
Soldering Iron
Resistors
Capacitors
Transistors
Speaker
GOAL
A discrete electronic alarm circuit assembled on a PCB that generates a siren tone using transistor-based oscillation.
MY APPROACH
I followed the circuit layout from the kit and soldered each component onto the PCB, including resistors, capacitors, two transistors, and the speaker. After assembling the board, I tested the circuit to make sure the connections were correct and that the alarm sound was working.
CHALLENGES
Ensuring I made clean soldered joints and also ensuring no two joints were accidentally soldered together to short the circuit
WHAT I LEARNED
How discrete electronic components interact to create oscillating signals and how PCB assembly and soldering techniques impact circuit reliability.
NEXT IMPROVEMENT
Make the PCB board more complex by making the soldered components more industry-level and smaller versus the lab components I used
