Here is my Arduino battery tester, designed to explore the performance of various types of batteries, including 18650 and acid-based ones. Successfully tested even with a 6V lead-acid battery with a capacity of 4.2A, this device provides battery capacity readings in milliampere-hours. In fact, it’s an old article that I had never published before, but I have revisited and decided to publish it now.
In this category I’m going to add all thing like:
Multimeters: Versatile tools for measuring voltage, current, and resistance. They can be digital or analog and are fundamental in any electronics workbench.
Battery Testers: Designed specifically to test the charge state, capacity, and health of various types of batteries.
Network Cable Testers: Used for testing the integrity and connectivity of network cables like Ethernet.
Continuity Testers: Used to check if there is a complete path for current flow in a circuit.
Oscilloscopes: For visualizing the waveform of electrical signals to analyze their characteristics.
Logic Analyzers: Used for testing and debugging digital circuits by capturing and displaying multiple signals from a digital system.
