DIY Amp / Watt Hour Volt Meter
With a Voltage Divider with R1 = 30k Ohm and R2 = 10k Ohm, A 12v battery would calculate as follows: 12v / Ratio = 3v on the A4 pin. 3v / .00488 = 615 (ADC Reading - round up) so A4 pin Voltage = .00488 * ADC reading (615 in this case), or 3.00 volts.
How To Test Amps With A Multimeter | AC and DC Amp
A healthy battery should maintain a reading above 10V. If the reading remains stable and doesn''t drop below this threshold, the battery is in good condition. However, if the voltage plunges, say to 5V, it''s a clear sign that …

How to Make an Engine from a Battery, Wire and a Magnet
Gather your materials. You don''t need any special tools to make a homopolar motor. All you need is a battery, a length of copper wire, and a neodymium magnet. You can use any kind of alkaline battery, but a larger battery, such as a C-cell, will be easier to hold.
HOW TO
To make our clock useful, we need a way to set the time after we power it up. To do this I used 3 switches. One cycles the clock through its 4 modes (normal, set, all-low, and all-high — explained later), one increments the hours, and one increments the minutes.
