Summary of 8051 PROGRAMMABLE POWER SUPPLY
The article describes an 8051-based programmable power supply project that converts keypad input into a precise 0-5V analog output using a DAC0808 digital-to-analog converter. The input value is entered via a keypad connected to port P1, processed by the microcontroller, and converted to an analog voltage. The output voltage is displayed on a 7-segment display connected to port P0, with a decimal indicator on port P2. Special keys allow for deleting input or triggering the voltage conversion, achieving voltage precision between 0.1V and 0.2V.
Parts used in the 8051 Programmable Power Supply:
- 8051 Microcontroller
- Keypad
- DAC0808 Digital-to-Analog Converter
- 7-segment display
- Connecting ports (P0, P1, P2)
- Power supply and supporting circuit components (resistors, capacitors, etc.)

Circuit Operation: Circuit diagram appears in the 0-5 the entered value from the keypad circuit, which is connected to port P1 applied to the integrated DAC 0808 DAC output is obtained from the analog voltage. P0 port is connected to the 7-segment display of the absolute value of the voltage, which is connected to port P2 indicator shows the decimal value of the voltage. On the keypad “*” key to delete the entered value, “#” key, the entered value is used to convert the analog voltage. Output of 0-5 V 0.1 V-0, 2Volt precision analog voltage is obtained.
