Controlling an HMC624LP4E RF attenuator using Arduino

Monday, July 16th, 2018

Kerry Wong writes: For simplicity, I used a single rotary encoder for controlling the attenuation. In order to prevent accidentally changing the set attenuation value, I used the built-in switch of the rotary encoder as the lock/adjust control. The idea is that the attenuation value can only be adjusted when...
