Digital Thermometer using Arduino and LM35 Temperature Sensor

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using Arduino Uno. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55...

Arduino Shield Tutorial – Make Your Own LCD Keypad Shield

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This is another practical tutorial, we're gonna build a fully working complete Arduino LCD Keypad shield, we're gonna go through all the steps, we'll start from scratch explaining and simulating the circuit diagram in Proteus,...
