Though the pool alarm system is efficient at retaining your children from going outdoors to swim we imagine that it is necessary to provide them swimming lessons. Accidents may happen and also you need your kids to be prepared no matter what might occur!
2. the speaker is linked to Arduino Uno digital pin 3 and GND. I’m using this speaker box for amplification of the sound. But you may also strive to connect it directly to a speaker without an amplifier, sound shall be very weak. SD card Chip Select or pin 1 is related to Arduino Uno digital pin 2 by this white wire. SD card MOSI or pin 2 is connected to Arduino Uno digital pin eleven by this black wire. SD card GND or pin 3 is connected to Arduino Uno GND pin by this brown wire. SD card 5V or pin 4 is related to Arduino Uno 5V pin by this pink wire. SD card SCLK or pin 5 is related to Arduino Uno digital pin 13 by this orange wire. SD card MISO or pin 7 is related to Arduino Uno digital pin 12 by this yellow wire. 4. The sound files is accessed utilizing the Arduino SD and SPI libraries. 5. The sound is performed to digital pin 3 by Pulse Width Modulation (PWM) utilizing the Arduino TMRPCM library. The default speaker output of TMRPCM is via digital pin 9. But since I’m utilizing a Keypad/LCD shield, digital pin 9 is already use as LCD enable pin. TIMER2. It will enable digital pin three as speaker output. UP button capabilities as Volume UP or increase the amount. The TMRPCM library allows a volume upto 7 but a volume of 4 is the maximum this setup may allow, above this is only a noise. DOWN button features as Volume DOWN or lower the amount.
