In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert. // first pic This ...

Every code here should run on every arduino board without problems. The sketches rely solely on the tone() function from Arduino, so the sounds are all monophonic. On the bright side, libraries are ...
