Thermohygrometer with clock and LCD display on Arduino UNO
techrm @ instructables.com has a tutorial on a nice thermohydrometer: These 7 steps will drive you through the "construction" of a thermo-hygrometer with clock on Arduino UNO. Data and time, humidity and temperature will be shown on a LCD 16x2 display .If you have purchased a LCD...
Continue ReadingThe New Arduino 101 (Genuino 101) – Unboxing, Set Up, and Comparing it to the Arduino Uno
Arduino's newest board, the Arduino 101 is finally here... It has an Intel Curie processor, and an on-board gyroscope, accelerometer, and Bluetooth. Let's see how it stacks up to the Uno, and find out what each of the components on the board do. At the end of the video, I go through...
