This is the circuit diagram of the digital clock using 8051 microcontroller. As we can see the microcontroller is connected to three 7 segment display with distinct ports not multiplexed and the last hour digit is only connected to a pin as it only shows 1. LED and buzzer are self explanatory according to the code.

Different temperature indicator project with discrete component is already published in www.electronicsproject.org. Now, here is a microcontroller based temperature indicator with LCD for better and precise reading. A temperature sensor DS1621 is used here for better result. As we know that programming language 'C' is less complicated with well-defined syntax in compare to Assembly language so we write program for microcontroller in 'C'.

Circuit description

The circuit of temperature indicator is designed around microcontroller AT89C52 where DS1621 is used as temperature sensor. The block diagram of temperature indicator using AT89C52 is shown in figure 1.

The temperature sensor IC₃ is used to sense temperature and read as 9-bit value. The pin 1 and 2 of sensor (IC₃) is connected to pin 11 and 10 respectively of microcontroller (IC₂) as shown in circuit diagram. The sensor (IC₃) activates its thermal alarm output in exceeding of user-defined high temperature until temperature drop below user-defined low temperature. Non-volatile memory is used to store user-defined temperature.

A crystal oscillator X_TAL1 is connected to X_TAL pin of microcontroller (i.e. pin 18 and 19) for operating of microcontroller. A high pulse on RST pin (pin 9) through capacitor C₅ is given while the oscillator is running for reset the microcontroller. Pin 31 is also connected to +Ve supply for execution of internal program. During flash programming at 12V programming is selected pin 31 is also used to receive 12V programming enable voltage.

The 16*1 LCD is used as display where VR₁ is used to control the intensity of display. The connection of LCD is given in table 2 where pin 15 and 16 is not used.

Software:- A cross-complier C51 version 7.10 from keil software is used here for compiling the program code written in C.
