1-Wire devices, such as the DS18B20 digital temperature sensor, are great to use with Arduino boards because you can connect many of them to a single IO pin. The freely available software libraries and example code make using 1-wire devices
I recently read a story about a wedding gift that gave a distance to a destination, and would not open until the destination was reached. It is based upon a mix of Arduino, a gps sensor, and good old inventiveness baked
LiquidCrystal lcd(12, 11, 10, 5, 4, 3, 2);
int backLight = 13; // pin 13 will control the backlight
I’ve been playing with my Cadmium Sulfide (CdS) photoresistors, and have put together a basic light sensor. I’m outputting raw values, so there is no correlation with solar insolation. If anyone knows some cool formulas that would convert the output to sun
A thermistor makes for a very inexpensive temperature sensor, under $2 for the thermistor and the 10k ohm resistor, not counting the $45 for the Arduino and LCD display: Become the Maker you were born to be.
Yesterday I received a package in the mail from Hacktronics. Call it an early Christmas present. Inside was a package of Thermistors, 10k ohm resistors, a breadboard, and a Ethernet/Micro SD card Shield. Stay tuned for a variety of projects
