For this project, you’ll need to write a program that tells the Arduino to trigger the camera and flash when it detects a sound. 2. Piezoelectric Sensor: This sensor will act as your sound detector.

I2C protocol makes it easier to connect more ICs using only 2 wires SDA and SCL and allows communication between them at relatively low speed. The I2C bus or TWI (Two Wire Interface) allows a single ...

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… ...

I checked the sensor line w/ a multimeter and it holds steady at 2.3V when the Panaflows are in there. It's about 1V with the Vantecs but it bounces around.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
