Basic Battery Voltage Reader with Arduino :: Student

9V is not a good input voltage to produce 5V through a linear regulator. The first problem is how to reduce that 9V to 5V that the Arduino board can use. Most Arduino boards have an external voltage input, and a range of 7-12V is recommended. So 9V seems perfect. The problem is that most Arduino boards use a linear regulator to drop that 9V to. We also used the trick of reff voltage to get the input voltage from the Arduino without using any analog inputs or components, looks like the complete package. All you have to is add the function that displays the indicator in the loop function and add the place where you wanted to display it and you are ready

Arduino Precise & Accurate Volt Meter (0-90V DC): In this instructable, I've built a voltmeter to measure high voltages DC (0-90v) with relative precision and accuracy using an Arduino Nano. The test measurements I took were accurate enough, mostly within 0.3v of the actual voltage measured with a A simple library for monitoring battery voltage in Arduino projects. Utilizes the 1.1V internal reference of the ATmega328 to accurately monitor battery voltage and current Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a standard 9V battery pack, as usual The default ADC full-scale voltage is 1.1V. To read higher voltages (up to the pin maximum voltage, usually 3.3V) requires setting >0dB signal attenuation for that ADC channel NOTE: regardless of the input used, Arduino has a 3.3 V output socket to power loads operating at this voltage; in fact a second regulator, right for the purpose of generating 3.3 V, is directly connected to the 5 V. This socket cannot be used as input

The Arduino reads the voltage sensor which is connected with the Battery and the Arduino then sends this data with the help of NRF24L01 to the receiver NRF24L01 Module, and then the Arduino takes the data and then the Arduino through Bluetooth Module sends this data wirelessly to the Android cell phone application.

Arduino uno four analog channels are used to measure four batteries. Note the ground of all the four voltage dividers and arduino are at the same level. If you do not connect the arduino ground with voltage dividers ground then the arduino adc circuit will not complete up. ADC pin will become floating and it will read raw. When connected to an Arduino, the 9V battery goes through a linear regulation to lower the voltage to an acceptable level. This alone would tax a typical 9V battery. It would do better with 3 AA batteries connected to the 5V input on the Arduino bypassing the regulator. But this is not to say that an Arduino cannot be modified and programmed to run successfully with a 9V battery.
