How can I prevent a 120VAC solenoid valve from resetting my ATMEGA328?
I'm using an ATMEGA328 running Arduino code to control a relay which uses a 5V signal to switch a 120 VAC solenoid. I added a flyback diode to the relay which fixed an earlier reset problem, but I'm ...

H-bridge with two logic-level GPIOs drawing high current
I am working on controlling a bi-stable latching solenoid with an H-bridge.
The microcontroller that I am using for my project doesn't have enough GPIOs for me to use four pins for the H-bridge, so I ...

Could I use a DC motor in place of a solenoid valve in a simulator?
I'm doing a project and using Proteus for simulation.
I wanted to use a solenoid valve but couldn't find the component in Proteus.
Could I use a DC motor instead?

Eliminating a weird pulse when switching a valve actuator using a low-side MOSFET
The circuit is connected as drawn below:
MOSFET IC = MAX14919A
Valve actuator = MHE2-MS1H-3/2G-M7-K
Schottky Diode = SS16HL-TP
The pulse happens when the low-side MOSFET opens (disconnecting the ...
