Overview The multimeter is an indispensable tool for any electronics project, as it helps overcome countless challenges during project completion. This article will demonstrate how to create a cost-effective digital multimeter using an Arduino board and an OLED display. This multimeter is capable of measuring voltage, current, resistance, and capacitance. Upon completing the project, you will have your own multimeter at the lowest possible cost. What You Will Learn Underst...

ADXL345 Accelerometer Module Features ADXL345 accelerometer sensor can measure angle orientation and object path. The sensor can do that in three X, Y and Z axes. It can also measure dynamic and static acceleration forces. Dynamic acceleration force is due to motion and vibration and static acceleration is caused by gravity. The sensitivity range of the ADXL345 accelerometer sensor is from +-2g to +-16g. (g is approximately 9.8) For example, when this sensor is placed on a flat surface, its value is +1...
