ATtiny85 Bargraph Voltmeter This article describes a simple bargraph display driven by an ATtiny85. It measures the voltage on an analogue input, and displays it by lighting up from 0 to 10 bars on the display. It could be used as a battery level indicator, or as the display for a sensor such as a thermometer:
