So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

Arduino Nano based rotation counter using an A3144 digital LOW output unipolar Hall effect sensor on interrupt 0 (pin D2) and a 1.3" 128 x 64 I2C OLED with an SH1106 controller using the simple text ...

Using the Pin Change Interrupt allows connecting encoders and buttons to any of the Arduino pins, not just the two External Interrupt enabled pins. While maintaining the ability of immediate reaction ...

And if you think about it, rotating an antenna and moving a solar panel, ... 12 thoughts on “ Antenna Rotation Arduino Style ” LB9MG says: August 31, 2016 at 9:27 pm ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...
