This Arduino battery voltage indicator indicates the status of the battery by glowing LEDs on a 10 Segment LED Bar Graph according to the battery voltage. It also shows your battery voltage on the LCD ...

Battery Indicator with Arduino UNO and Tiny 0.42" 72x40px SSD1306 OLED Display - upiir/arduino_oled_battery_indicator ...

In case the battery rapidly drops its voltage significantly under load, it would require a replacement. This circuit will function as a comparator and will measure the car battery voltage with an ...

A Battery-status Indicator circuit can be useful, mainly to monitor portable Test-gear instruments and similar devices. LED D1 flashes to attire the user’s attention, signaling that the circuit is ...

Once you have soldered your kit together, it’s time to start monitoring your battery levels. For this example, we will be hooking up the indicator to a 3.7V lipo battery that is powering an Arduino ...

In this article, we will learn how to design a simple 12V battery charge level indicator using Op-Amp. Although the Battery level is an ambiguous term because we can't really measure the charge left ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects.

But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino Uno and a 9V battery, plus a current-limiting resistor and the all-important buzzer.
