The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N,
allowing it to achieve high-quality sound reproduction. The new
filterless architecture allows the device to drive the speaker directly,
requiring no low-pass output filters, thus saving system cost and PCB
area.
With the same numbers of external components, the efficiency of the
PAM8403 is much better than that of Class-AB cousins. It can extend
the battery life, which makes it well-suited for portable applications.
The PAM8403 is available in SOP-16 package.

const int ledPin = 13; // the number of the LED pin
// Variables will change :
int ledState = LOW; // ledState used to set the LED
// Generally, you shuould use “unsigned long” for variables that hold time
// The value will quickly become too large for an int to store
unsigned long previousMillis = 0; // will store last time LED was updated

// blink the LED.

Grafik hasil pengukuran (sekitar 30000 sampel pertama). Nampak amplitude maksimum berubah-ubah, tergantung posisi dan tekanan jari pada sensor.
Grafik hasil pengukuran (hanya sekitar 1000 sampel pertama saja). Nampak ada noise pada hasil pengukuran.
Rentang angka ADC adalah 0 sampai 1023 (ADC 10 bit di ATMega328)
Angka maksimum yang tercatat adalah 536. Angka minimum yang tercatat adalah 496. Rentang angka yang tercatat adalah 40. Hal ini konsisten dengan hasil tampilan dengan software Processing di artikel Sensor Detak Jantung yang menunjukkan rentang angka pengukuran sempit dibandingkan dengan sensor asli.

Berikut ini adalah sensor temperatur NTC K524 yang ditemukan di Jaya Plaza. Harganya lumayan murah, di bawah Rp 10 ribu.
Pengukuran di temperatur 24 derajat Celcius menghasilkan resistansi 41.6 ohm.
Sensor dihangatkan dengan cara digenggam dengan tangan, hasilnya resistansi turun ke 33 ohm. Temperatur tangan kira-kira sekitar 35 derajat celcius menurut termometer GM320.
Spesifikasi NTC K524 menurut http://en.tdk.eu/tdk-en/176900/products/application-guides/consumer—epcos-brand/home-appliances/ignition-units-for-gas-cookers/ntc-thermistors adalah sebagai berikut:
Sensor ini non-linier, sehingga untuk konversi resistansi ke temperatur akan memerlukan software khusus. Cocok untuk percobaan dengan board Arduino Nano.

HOW TO SOLDER

C870 ini adalah sebuah sensor temperatur PTC (Positive Temperature Coefficient), artinya makin panas maka makin besar resistansinya. Menurut datasheetnya, komponen ini umumnya dipakai sebagai pembatas arus. Mekanismenya adalah arus pada PTC menghasilkan panas, dan panas ini akan menaikkan nilai resistansinya. Jika nilai resistansi tinggi, maka arus yang mengalir akan berkurang.
