Mount for Arduino Uno, half size breadboard, and small panel mount potentiometer. Many Arduino projects require a potentiometer and I always struggle using a trimmer or needing two hands to use a panel mount that is hanging off the side of the breadboard. This mount will firmly hold an Uno, a half size breadboard, and a small panel mount potentiometer (like https://www.amazon.com/dp/B06WWQP12J). Solder wires to the potentiometer leads (I cut one end off of Dupont type breadboard jumper wires), place it in the mount, snap on the cap that keeps the potentiometer in place, push on the knob, then snap in the Arduino Uno and breadboard.
