This is fully customizable 3D printed Memory stand which consists of various sensors and arduino which make it a Smart memory Stand
Who can Use this?
Sometimes we forget things like wallet,keys,medicines etc. at home when we are leaving for office or anywhere else. Aged people face this problem more often. Smart Memory Stand can be used by anyone who need to remember something as a part of daily routine
How this works?
Say for example, you need to remember following things for the next day
1. Take medicine after breakfast (at 8:30AM)
2. Call Mr.John for Plumbing work at your house
3. Take wallet, extra keys of house with you
So you can put your keys, medicines in pre-defined slots of memory stand and it will remember these things for you using following electronics
Memory stand consists of various sensors and arduino UNO
1. Real-Time Clock (I2C RTC+EEPROM Board(DS3231+AT24C32)): It will provide signal to the system on pre-defined time. Lets say, medicine at 8:30AM and 9PM, call Mr.John at 9AM etc
Indication on specific time can be done by blinking LEDs or buzzer or pre-recorded voice
2.Ultrasonic sensor (HC-SR04): This sensor detects human proximity and it will start its operation when human goes near it. Lets say, you need to remember to take keys which you have put in slot so when you will go near the stand, LED with keys it it will start glowing so that you can remember to take keys
2. IR object sensor: This sensor will be used to check whether the object is present in its slot or not
> 2 IR object sensors are attached with a strip which is attached with a servo motor. Servo motor will rotate at +25 deg and -25 deg from its center position so that using only 2 IR sensor all 6 slots can be checked (Square holes in center up and center down slots & hollow round in left and right side slots are for IR sensors
This design is completely customizable as you can make it with your name just as I made it with my name Mr.Bhatt
It can be made for more than 6 number of slots too. As IR sensors are attached with a servo motor, you can check more than 6 slots using 2 sensors if you re-program the servo
You can add your voice with this device which will remind you of your things on specific time
You can also add this device with IoT using ESP8266 or any other Wi-Fi module so it can also help you remember something when you are not at home
Combinely, this device is a solution for you if you often forget daily routine things, which we all do.
