Please see License File for more information. If any one of these being monitored falls within a certain range, the seven segment display on the touch screen will turn red indicating which one is out of range, and a buzzer will sound to get your attention. Connects to phone via Bluetooth 4.0 when. This is the tested parameters and calibrations for given devices Device The purpose of this project is to monitor Oil Pressure, Engine Temp, Fuel Pressure and Battery/Alternator Volts. Requires FREE APP Download Check the status of your car battery (or any 12V battery) using free cell phone APP. If they are different, you will need to increment or decrement the conversion factor until the measurements match. If the measurements (library and voltmeter) match, the conversion factor is right. Print the voltage obtained by the lib through getBatteryVolts method.Measure the voltage of the battery with the voltmeter.To find the right conversion factor you will need a voltmeter. The port can change according to the hardware you are using.

#Arduino car battery monitor code

Your code is using the wrong conversion factor.

Your code is using the wrong ADC port or.

To program the ATtiny, Im using an Arduino Uno that is programmed with the ISP sketch.

There are two main problems that could be happening: On ebay, I stumbled upon a popular type of battery monitor LEDs. Sometimes the result of getBatter圜hargeLevel and getBatteryVolts may not represents the real state of the battery. } Troubleshoot and Finding Conversion Factor print( 'Charge level (using the reference table): ') Default value: falseĪttention! Using predefined conversion table will consume more RAM than using the formula. Parameter bool useConversionTable: Indicates if the internal charge level will be obtained using the internal predefined conversion table instead the formula (default).Returns the current battery charge level. Method int getBatter圜hargeLevel(bool useConversionTable = false) Default Value: 20 Īfter the installation and instantiation, we are able to obtain the charge level and current battery voltage. reads (optional): Quantity of reads to get an average of pin readings.This value can be obtained through comparisons between code result and a voltmeter result. conversion_factor (optional): Value used to convert ADC pin reading in real battery voltage.adc_pin (optional): The ADC Pin that lib will read (analogRead) to calculate charge level.
