High folks, I am currently developing the electronics to read a cryogenic liquid level sensor. This sensor uses the change of capacitance between two electrodes to determine level of the liquid. I have designed a circuit using a LM555CM to generate a square wave read by PD5 on the ATMEGA328P. I jus…
