This March LitDev introduced about Arduino on this blog.  Today, I'd like to introduce my Small Basic programs using Arduino.

The first one is the IR Turtle controller ( HLT038 ).



The circuit is like ( GZN399 ):



The Arduino program irdemo.ino is from osoyoo.com .  More details about this program are described here .

The second one is a thermometer ( KKK886 ).



The circuit is like ( GZN399-0 ):



The Arduino program is as follows.

//TMP36 Pin Variables
int sensorPin = 5; // the analog pin the TMP36's Vout (sense) pin is connected to
// the resolution is 10 mV / degree centigrade with a
// 500 mV offset to allow for negative temperatures
float lastTemp;    // last temperature

/*
* setup() - this function runs once when you turn your Arduino on
* We initialize the serial connection with the computer
*/
void setup()
{
Serial .begin(9600);  // Start the serial connection with the computer
// to view the result open the serial monitor
}

void loop()                     // run over and over again
{
//getting the voltage reading from the temperature sensor
int reading = analogRead(sensorPin);

// converting that reading to voltage, for 3.3v arduino use 3300
int mV = map(reading, 0, 1023, 0, 5000);

// now print out the temperature
float temperatureC = (mV - 500) / 10.0 ;  //converting from 10 mV per degree with 500 mV offset
//to degrees ((voltage - 500mV) times 100)
if (temperatureC != lastTemp) {
Serial .println(temperatureC);
lastTemp = temperatureC;
}
delay(1000);                                     //waiting a second
}

Arduino can be connected with many types of sensors or actuators.  So, with this device, we can explore Small Basic world more and more interesting!
