Practice making DIY- GC 0 164 --Bluetooth -APP automatic washing machine water level detection
Design based on STM32 single-chip microcomputer--- Bluetooth-APP automatic washing machine water level detection
2. Function introduction:
Hardware composition: STM32F103C single-chip minimum system + LCD1602 display + 1 5V DC motor (low-speed laundry and high-speed dehydration) + 1 water filling solenoid valve + 1 drainage pump + buzzer + LED indicator + 1 floating ball water level sensor + Multiple buttons (standard washing, quick washing, separate dehydration, stop) + HC-05 Bluetooth module (only available in Bluetooth version)
1. There are 3 washing modes: standard, fast, and separate dehydration. Each mode of laundry is different
(1) Standard washing function: the total time is 10 minutes. Add water (the time is not fixed), strong washing for 5 minutes, weak washing for 3 minutes, draining for 1.5 minutes, and dehydration for 0.5 minutes.
(2) Quick washing function: the total time is 5 minutes. Add water (the time is not fixed), weakly wash for 3 minutes, drain for 1.5 minutes, and dehydrate for 0.5 minutes.
(3) During strong washing/weak washing, the motor rotates forward for 10 seconds, stops for 5 seconds, reverses for 10 seconds, stops for 5 seconds, and cycles. The difference between strong and weak is that the speed of the 5V DC motor is not the same.
(4) Press the separate dehydration button to dehydrate independently, and the 5V DC motor will run at high speed in one direction during dehydration.
(5) When draining and dehydrating, the drainage pump is powered on to pump out the sewage to the drain outlet.
(6) When adding water, the water filling solenoid valve is opened until the float type water level sensor detects that the water has been added in place, and then the water filling solenoid valve is closed.
2. Through the button or the Bluetooth mobile APP (only the Bluetooth version can choose the laundry mode.
3. LCD1602 or Bluetooth mobile phone APP (only available in Bluetooth version), display the current mode and running status. operation hours.
4. Standard and fast washing modes, the premise is that the water level can meet the requirements.
5. After the laundry is finished, the buzzer alarm LED lights up.
