For this week, we had a problem regarding the
motors, one of them had been broke because of the over electric flow. We had
put the current too much or over the limit for the motor. It is our mistake for
not check the current flow for the transformer. We had overcome the problem
with buy the new one and also read carefully the data sheet for the transformer.
We also start to make the alarm sensor circuit.
We also start to make the alarm sensor circuit.
Alarm button.
This circuit is function to alert
the people around when we get disturb or in dangerous situations like getting
assault. The circuit will function when we push the button and the circuit will
produce police alarm sound. It will scared the criminal because they can
attracted the people around.
The component we used is
Resistor 10M, 100k, 1M, 47k, 100ohm, capacitors,
electrolytic capacitors, NPN transistor, push button switch, switching diode,
and ic LM358.
