This post is in response to a reader who asked about detecting mains electricity using a microcontroller. The easiest and safest way to detect mains electricity using a microcontroller is with an ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

Voltage-gated channels open paths for ion permeation upon changes in membrane potential, but how voltage changes are coupled to gating is not entirely understood. Two modules can be recognized in ...

Out of curiosity, I bought a strain gauge sensor module after it appeared on sale. This write-up is fuzzy, since I decided to write based on a quick inspection of it. Have fun reading my little post ...
