In this example we will connect an LM35 temperature sensor to our Arduino The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large […]
Making a Touch Sensitive On/Off Circuit With Bare Paint and a 555 Timer IC: In this tutorial we are going to make a simple touch sensitive circuit using some Bare Paint, a 555 timer circuit, a couple of resistors, a LED and a capacitor.
