Sound Activated Timer Switch Code. Since the Grove Sound Sensor produces a varying voltage, we can use the microcontroller’s analog-to-digital converter (ADC) to handle that voltage. So, here is a ...

It weighs more than three times the Nano at 25 grams and has a larger footprint, with a length of 68.6 mm and a width of 53.4 mm. With its ports, the Uno stands at a total height of 15.4 mm ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

sound sensor 1 Articles Megavallometer Camera Trigger. July 17, ... Once connected to his camera he selects one of the three trigger programs, and the Arduino handles the rest.

Each sensor can be communicated with using I2C from analog pins 4 and 5 on the Arduino Uno. We powered the sensor stick using the 5 volts out available on the Arduino Uno.
