Analog panel meters are arguably not as blingy or flashy as LEDs, but their simplicity adds a touch of elegance and makes them easier to read quickly.
First up, the Voltage Panel Meter!
This Small -15V to +15V Panel Meter is about handheld-size, with three screws to open up the panel and replace the backing paper, if you like. It’s great for analog projects that have a split power supply or large voltage swings.
The back is constructed with two bolts the left coil is marked below with Negative to distinguish the positive from the negative. You can wrap a wire around the bolt and use the nuts to keep them in place, or use alligator clips.
Up next, the Current Panel Meter!
This Small -1 Amp to +1 Amp DC Current Analog Panel Meter is handheld-size, with three screws to open up the panel and replace the backing paper, if you like.
Great for measuring larger bidirectional current draws, perhaps to and from a battery bank or generator. Of course you can use it just fine with uni-directional current draw as well, either positive or negative currents.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
