The COVID-19 pandemic has reserved our habits and our way of living social relationships
72.3% of the population is very or extremely concerned about the spread of Covid-19. This is one of the data that emerges from the survey conducted by the Hacking Covid-19 group on the impact of the pandemic on people's habits and sociability. Professionals from various fields, from psychology to marketing to communication, have joined forces and skills to investigate the consequences of what is, in all respects, a social, as well as health and economic, emergency.
In the drama of the Covid-19 pandemic there is also a positive note: education in new technologies in people and businesses that until yesterday were the most refractory to their use.
This idea came to me while I was in the elevator and I saw that many buttons were selected by different people.
I asked myself: can I press the button without touching it?
I gave an answer to this question by creating Notouchmaks, a project that uses an ultrasound sensor to understand the distance of the hand, the formula for understanding the distance is s = v * t (v: speed, s: space, t: time)
I also used an LCD to see the chosen plan and some LEDs to confirm the choice.
The elevator buttons are pressed with the servomotors, I managed 3 of them for 6 buttons.
I inserted the motors in the center of the structure to maximize spaces and mirrors, all this controlled by an Arduino MKR1400CONNECTIONS
The connections are very easy to make.
Now built the structure with a 3d printer for the case in which the electronics and a laser are located to create the iron structure that was welded with a hydraulic press.
After assembling everything and setting all the pieces together, the moment of the final test arrives, I positioned the project near the wall with a sheet of paper from below to simulate the button panel of an elevator. It was enough for me to put my hand near the sensor to choose the plane, I put ranges for each plane, so the closer we get the more the plane will be lower, the further they move away the more the plane will be higher. If I postpone a long time on a choice, the plan is confirmed and with the green LED there will be confirmation and the servo motor will press the button.
I like to have fun making this project I hope you enjoyed it!
I made this project with all the materials I had at home, the upgrades that I would like to do for a 2.0 version are:
• Use an ARDUINO NANO 33 BLE SENSE because a many built-in sensors with for example the microphone: to acquire and analyze the sound in real time a sensor for gestures, the environment, the color of the light and the light intensity sensor: stimulate the pressure of the room, but also if someone is approaching the table
• Add deep sleep mode to maximize autonomy
I hope you liked the project, for advice or question you can contact me here = firstname.lastname@example.org
