But Arduino processors such as ATmega328/ATmega168 don’t have DAC inbuilt. Arduino has ADC feature (Analog to Digital Converter) but it has no DAC (Digital to Analog Converter). It has a 10-bit DAC in ...

This project help you to build a Power and Swr Meter (for HF) using Arduino Uno R3 (or compatible ... thanks to the volt watt conversion table written in the source code. This values are valid using a ...

Looking for a digital recreation of the classic analog volume unit (VU) meter? If you’ve got an Arduino, a few passive components, and a SSD1306 OLED, then [mircemk] might have the answer for you.

[hamblin.joe] wanted to do a simple project for kids along these lines, so whipped up a neat design using analog meters to display the time. The build relies on that old stalwart, the Arduino Uno ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

Any radio amateur knows the importance of an accurate RF power meter ... optimum input SWR over a wide frequency range. A pre-programmed microcontroller type PIC16F876 with built-in 10-bit analogue to ...
