Abstract: : Thispaperpresentsthedesignanddevelopment of a microcontroller-based digital weight measurement system using an industrial-grade strain gauge load cell. The system utilizes the Arduino Uno platform, an AD620 instrumentation amplifier, and a 16x2 LCD for real-time weight display. A regulated 10V excitation supply is provided to the load cell using a7809voltageregulator,andtheoutputsignalisamplifiedto a suitable range for analog-to-digital conversion. The digitized data is then processed through calibrated software logic and displayedinrealtime.Thesystemwastestedforweightsranging from 0 to 200 kg, demonstrating good linearity, repeatability,andoperationalstability.Theobjectiveistoprovidealow- cost, scalable solution for applications in industrial weighing, small businesses, agriculture, and educational labs. The system’s modular design allows for future enhancements, such as wireless datatransmission,IoTintegration,andimproveduserinterfaces. Results confirm the viability of the proposed approach as an efficientalternativetoconventionalcommercialweighingsystems
