Serial Kickstarter entrepreneur Patrick Thomas Mitchell has once again taken to Kickstarter to raise funds to take his new programmable Arduino ultrasonic experiment kit into manufacture.
Once assembled the kit allows you to choose between four different modes which are demonstrated in the video below. Pledges start from just C$36 for the DIY kit and fully assembled and tested development boards are available from C$65 with shipping expected to take place during February 2017.
Patrick explains a little more about the new Arduino ultrasonic experiment kit and its functionality :
This bad boy can be re-programmed with your own code, and the included code samples can be edited to fit your project! It comes with four programs installed on the included ATMEGA328-PU chip. Those programs are:
Servo Motor Sentry Mode:
In this mode, you can interface the HC-SR04 ultrasonic ping sensor with a servo motor and the main board (Only some reward tiers include the extra servo motor PCB and servo motor kit). When powered up in this mode, the ultrasonic sensor transmits and receives data. The servo motor turns back and forth. If something comes within 40cm of the beam, then the servo motor stops, the on-board buzzer starts to beep, and the LCD reads “OBJECT DETECTED”. This will continue until the object, or person is removed from the field of view of the ultrasonic sensor beam.
Security Mode:
In this mode, you place the Ultrasonic Experiment set facing an object up to 200cm away, and press the “SEL” button to take a sample of the distance. Once the sample has been acquired, the LCD turns off. When someone or something comes within that fixed distance, the buzzer turns on, and the LCD reads “SECURITY BREACH”. After a few moments, the program resets!
Sound Versus Distance Mode:
This is one of my favourite modes! In this mode, when you hold down the “SEL” button, the unit beeps at different frequencies based on how close an object is to the ultrasonic bream. If an object is within close proximity to the beam, the frequency of the beeping is very fast. If the object is far away, then the frequency of the beeping is slow. If an object is too far away, the buzzer doesn’t beep at all. You can try this in the dark, if you’d like!
Ultrasonic Range Finder Mode:
This is the most basic of modes. When you power the Ultrasonic Experiment board up in range finder mode, the LCD will read out the distance between the sensor and the object that it is lined up with in centimetres. It continually reads the distance over and over until powered off.
