I'm working on a project where I aim to measure resistances using an Arduino Uno. I started with two separate voltage dividers, each using a 1 MOhm reference resistor, connected to a common Arduino GND and 5V, and interfaced with Arduino analog inputs 0 and 1. P...
Battery capacity measurement can be useful in many situations. And it is not hard, only requires enough time to discharge battery completely with know resistance and a way to measure voltage in the circuit. Ohm's law will to the rest:I = U / R Let's say, we want to measure standard ...
4) Without my interaction, the circuit and it's microcontroller adjusts itself to the required voltage (24V) How can I measure the required voltage without checking the battery label? arduino batteries battery-charging charger Share Cite Follow asked Oct 9, 2018 at 6:28 ARMAT...
This Arduino based current, voltage, and power sensor/meter tutorial was created for hacktronics by Steve Spence. For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial products that can do th...
Before you can control the temperature, you need to measure it. The most common method used in the RepRap community is to use a NTC thermistor. With the help of the circuit shown below, the AVR can measure a voltage, which depends on the used resistors and the temperature at the ...

However, the bus capacitance is not easy to measure. As a result, it might be difficult to calculate the correct resistor value. To find a usable resistor value, start with a high pullup resistor to I²C bus and then reduce it until the best value. For example: start with 10K and ...
develop the process and measure yield. The idea of this kickstarter is to increase production volume to allow rock bottom pricing. If we meet our kickstarter goal we will be able to produce in volumes sufficient to offer Butterfly and Ladybug at prices competitive with the STM32 Nucleo ...
