The algorithm in this microcontroller design this design drives an LED matrix and provides digital-voltage-readout and bar-like dot displays, showing dots for a graphical output if the input value is ...

The construction of the device uses PIC16F676 for reading analog signal such as voltage, and displaying the 3-digit output by using 7-segment LED. On the hardware part, the PIC16F676 has 10-bits 8 ...

This circuit uses two National Semiconductor LM3914 dot/bar-display-driver ICs to implement a two-digit, 0 to 5V LED voltmeter that mimics a subranging flash ADC. An LED bar graph comprising five LEDs ...
