Hi
HC-06 datasheet says that LED blinks when the module is in either AT command mode or is not connected/paired. When it gets paired/connected LED remains steady ON.
GANEEV SINGHParticipantHi
Yes it is possible to process the recevied data and then display it on LCD.
Check out this project on EG: https://www.engineersgarage.com/contribution/xbee-wireless-joystick-control-distance-measuring-robot
GANEEV SINGHParticipantHi
This gyro sensor modue communicates via I2C ptotocol. You can read about I2C protocol in this link: https://www.engineersgarage.com/blogs/comparison-between-serial-communication-protocols-spi-i2c-uartusrt-0
Also, do check out it's pin configuration here: https://www.robotshop.com/media/files/pdf/rm-g145-users-manual-rm-g145.pdf
GANEEV SINGHParticipantHi
Check out this project, https://www.engineersgarage.com/mygarage/arduino-based-automatic-temperature-fan-speed-controller
You can also look out for a microcontrollerless project, here is it's ink: https://www.engineersgarage.com/contribution/experts/temperature-controlled-system

Controlling a DC motor's position requires a feedback circuit along it.

GANEEV SINGHParticipantHi
Well, this all what is required to make such a project work. Now you can place an object in front of the sensor and move it forward/backward; then see whether LCD is displaying the correct distance or not.
GANEEV SINGHParticipantHi
I guess you are asking about fuse bits of the microcontroller. Here's a link on EG which might help you:

GANEEV SINGHParticipantHi
If you are talking about DC motors then yes they rotate in both clockwise and anti-clockwise direction. It all depends on the polarity of voltage provided to a DC motor.
GANEEV SINGHParticipantHi
This code is written in order to read a sensor value (must be a humidity sensor here) and display "Rel.Humidity" on a LCD.
In this code average of 11 consecutive sensor readings is made and then it is converted to relative humidity value by means of some sort of a formula. This all is happening inside display() function.
Since 8051's don't have inbuilt ADCs therefore an 8 bit ADC IC must be connected to it with PORT1.
GANEEV SINGHParticipantHi
You can use a very common temperatrure sensor, LM35. Check out for it's various projects on EG portal. You can easil et this sesnor from online shps or if you live in new delhi then Bhagirath Place is the hub for all such things, visit there, you will love it.
GANEEV SINGHParticipantHi
For such cases, where high current and voltage are needed, I make use of BJTs/MOSFETs. Make them work like a switch (trasistor as a switch).
GANEEV SINGHParticipantHi
Generally servo motors work on 20ms pulse cycle out of which the ON time decides it's angle. PWM concept can be used in such cases.

Here are two projects that might help you:

2.https://www.engineersgarage.com/embedded/avr-microcontroller-projects/interfacing-keypad-circuit
GANEEV SINGHParticipantHi
There is no UIR bit in Register B; it's 5th bit is UIE which means-
Update-Ended Interrupt Enable (UIE): This bit is a read/write bit that enables the update-end flag (UF) bit in Register C to assert IRQ. The RESET pin going low or the SET bit going high clears the UIE bit. The internal functions of the device do not affect the UIE bit, but is cleared to 0 on RESET.
GANEEV SINGHParticipantHi
In this project, majorly PORT0 and PORT1 of microcontroller are being used. For connecting a DC motor via L293D cip you can make use of either PORT2 or PORT3 or you can also amke use of emaining pins of PORT1, as you require only two pins to control motor.
Secondly, you don't require a brand as such for a keypad; a normal 4X4 keypad would work fine. You can either build one or purchase it. Here's a link to buy it online:
