After uploading the code the Piezo will start making short beeps. On bright light the Piezo will only beep and on dark light it will be short. Some ideas for this experiment: Alarm for Lights in the ...

Now is the time to see the sample code (Arduino Uno/Nano Sketch)… [code] #define ALERT_LED 13 //SIGNAL LED . void setup() { TCCR1A = 0b10110010; TCCR1B = 0b00011001; ... Using pulsed light enables the ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

PIR Pin “out” connects to Arduino Digital 2. Here is the Arduino code for the Parallax sensor. int motion_1 = 2; int light_1 = 13; void setup(){ pinMode ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...
