Description

Circuit diagram like in figure 1 above is Circuit Diagram NiCad-NiMh Battery Monitor using LM3914 IC. The simple project can be used as test gear. Its easy way to monitor the battery voltages, especially dry cell, NICAD, NIMH, supply up to 1.5 Voltage. Battery Monitor range 0.15V to 1.5V. The project is built around Texas instruments LM3914, The LM3914 senses the voltage levels of the battery and drives the 10 light emitting diodes based on the voltage detected on input connector. Circuit works on 5V DC. J1 Jumper is used to select the DOT mode or bar graph mode.
