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 ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons. The goal here was to keep things as simple as ...

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.

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.

Users will need to provide their own Arduino Pro Mini and the hardware features a 1.4 W, 8 Ohms, Texas Instruments TPA2005D1, 14 bit ganged PWM, PWM 8 kHz low pass smoothing filter all powered by ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

What you’ll learn: Arduino’s new QWIIC-based UNO Plug and Make Kit is simple to use and can be up and running in the cloud in 10 minutes. A 48-MHz, 32-bit Arm Cortex-M4 from Renesas features ...
