Ultrasonic distance sensor with different distances
Good morning friends!!
Today we present to you an electronic project consisting of an alarm that is activated when it detects an object less than 40 centimetres away.
The elements are:
When the sensor detects an object less than 40 cm away, it sends a HIGH signal to pin 2 of the Arduino, which we have programmed to send in that case a HIGH signal, through pin 3 that activates the speaker in order to sound the alarm.
This way the parking sensors work, also a Lunar Rover, could use it not to collide with rocks.

App animals and sounds
Good morning,
Today we present you a design of an app. It has buttons with photos of animals and vehicles. When you press the photos the sounds are emitted.
The animals have been downloaded from google images, eye of the initial grid, so that they are small, selecting the image with the right button and save image as.
In App inventor we have to put buttons, deleting the text and putting of image of the button the photos of the animals.
Then in average, we drag the 8 sounds, assigning to each sound a sound, by means of the command source.
You can see the designs and the blocks below:
