If you started out working with electronics in an industrial environment, soldering may seem like a pain, and using a solderless breadboard means the potential for wires to come loose. If you long to instead use screw terminals for your maker projects, featuring positive locking without the need to heat up an iron, here’s a solution for you in the form of the Arduino Screw Terminal Shield, available in red or blue!
Ironically perhaps, the shield is offered as a kit that requires some soldering to put together. After that though, it allows access to all of the Arduino UNO’s pins, including the extra pins on the R3 board without having to solder or worry (as much) about whether something will stay plugged in. It also accommodates wire sizes between 24 and 14 AWG, which would include sizes much larger than what would normally be used with a breadboard.
