Hello Sir,
Its an easy task for me. My previous job(example 7) was similar to your in which we were detect the mass of water in a bottle, convert it to volume(V= mass/density), display it to LCD and send the readings to a smartphone via Bluetooth
in your case, we can use LCD or oLED(0.9") and for the motor, we can use driver IC or relays even we can change their rotation.
I have 4 years experience in PCB designing in EAGLE( single multilayer and flex).
following are some examples of my work
1. ESP12E wifi + relay board + humidity&temp sensor Smart module
2. ESP12S wifi + relay board home automation board.
3. ESP12E wifi + RC522 RFID + BUCk converter module.
4. atmega328au + hm11(BLE)+ relays car actuator module.
5. atmega328au + nrf24l01 + relays smart switch module.
6. atmega328au + mpr121 capacitive touch smart remote.
7. amega328au + LCD display + hc06(later hm10) + amplifier + strain gauge water mapping module.
8. atmega328au + hm10(BLE) + gyroscope + reed sensor + battery charger smart skateboard module
9. Arduino Uno clone.
I will provide you all necessary files ( CODE, gerber, smd-coordinate, BOM, Eagle(.brd& .sch) and 3D files ).
please, see my portfolio for more sample of my work.
or initiate chat for more detail discussion on your project.
thanks.
