Digital Multimeters (DMMs) User Guide 101

Digital Multimeters (DMMs) User Guide and Working Principle. A digital multimeter (DMM) is an electrical test instrument that can measure more than one electrical property. See Figure 1. Basic DMMs measure voltage, current, and resistance. Advanced DMMs include additional measurement capabilities, such as capacitance, continuity, and temperature. They may also include special functions, such as […]

Arduino based Tiltmeter

Arduino based Tiltmeter using MPU 6050 Accelerometer (DIY)   A tiltmeter (or inclinometer) is a sensitive meter for measurement of change in inclination angle. This project is about to design and implement digital tiltmeter that can sense the tilt from -180 to 180 degree on dual axis. Accelerometer is used as tilt sensor. Arduino UNO is used for programming and converting […]
