Summary of 8051 PROGRAMMABLE POWER SUPPLY
This article describes an 8051-based programmable power supply. The system uses a keypad to input values, which are processed by the 8051 microcontroller via Port P1. An integrated DAC 0808 converts these digital inputs into an analog voltage output ranging from 0 to 5 volts with 0.1-volt precision. A 7-segment display connected to Port P0 shows the absolute voltage value, while Port P2 indicates the decimal part. Specific keypad keys function as delete ("*") or execute ("#") commands for the conversion process.
Parts used in the 8051 Programmable Power Supply:
- Keypad circuit
- 8051 Microcontroller (Port P1, P0, P2)
- DAC 0808 Integrated Circuit

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.
