Summary of LCD DISPLAY FAN CONTROL CIRCUIT PIC16F84A PICBASIC PRO
This project uses a PIC16F84A microcontroller and DS18B20 temperature sensor to display ambient temperature on a 16x2 LCD, sound an alarm when a user-set temperature is exceeded, and control a fan to maintain the desired temperature. User setpoints are saved to EEPROM to survive power loss, and plus/minus buttons adjust the target temperature. Files include schematic, PCB layouts, Proteus simulation, and PicBasic Pro source code.Parts used in the LCD DISPLAY FAN CONTROL CIRCUIT PIC16F84A PICBASIC PRO:
- PIC16F84A microcontroller
- DS18B20 temperature sensor
- 16x2 LCD display
- Buzzer or audible alarm
- Fan (DC)
- Plus (+) button
- Minus (-) button
- EEPROM (internal to PIC16F84A or external if used)
- Power supply components (regulator, capacitors)
- Transistor or driver for fan
- Resistors and pull-up for DS18B20
- PCB and connectors

This circuit and the microcontroller PIC16F84A DS18B20 temperature information is obtained using the temperature sensor. 16X2 LCD screen showing temperature information obtained from user-specified temperature is exceeded audible warning. The ambient temperature value drops to the desired level of the fan keeps up. In addition to user-specified EEPROM heat value recorded in any power outages, loss of information is prohibited. Plus (+) and minus (-) buttons required for the operation of the fan allows you to set the temperature level.

- How is temperature measured in this project?
Temperature is measured using a DS18B20 temperature sensor connected to the PIC16F84A. - How is temperature displayed to the user?
The measured temperature is shown on a 16x2 LCD display. - Can the user set a target temperature?
Yes, the user can set the target temperature using plus and minus buttons. - Does the system provide an audible warning?
Yes, an audible alarm sounds when the measured temperature exceeds the user-specified value. - How does the fan respond to temperature changes?
The fan runs to lower ambient temperature when the temperature exceeds the desired setpoint. - Are user settings preserved during power loss?
Yes, the user-specified temperature is stored in EEPROM to prevent loss during power outages. - What software and files are provided with the project?
Provided files include schematic, PCB layouts, Proteus simulation, and PicBasic Pro source code, available in a ZIP download. - Is there a simulation available for this circuit?
