Arduino Thermometer in 3 minutes

Building a simple thermometer with Arduino is very easy. For this project I use: • Arduino Mega board • LM35CZ sensor Searching on Google “Arduino LM35” you can find this page on Arduino Playground. So I use this equation: temp = (5.0 * analogRead(tempPin) * 100.0) / 1024 As you can see on the Playground this is the most inaccurate

Programming ESP8266 with the Open SDK – Intro

Bought a ESP8266 just to use it paired with Arduino? Too bad! For less than 5 euros, it packs a 32 bit general purpose CPU and everything you need for WiFi connectivity (TCP/IP stack, WEP, WPA etc.) and 16 GPIO. It is generally accompained by a flash memory which contains the firmware. It is really
