Analog panel meters may not be as showy as LEDs, but their simplicity brings an elegant touch and makes them super easy to read at a glance. This extra-large 5V analog panel meter is about handheld size. You can easily open the panel with one screw and replace the backing paper if you want. Even though it's made for analog signals, it can also work with digital signals. Just send a PWM signal from a 5V logic microcontroller. As long as the frequency is 1KHz or faster, it'll work great. The back has two bolts with Positive and Negative marked below the coils. You can wrap a wire around the bolt and use nuts to secure it, or use alligator clips.
Using this extra-large 5V analog panel meter is a breeze. If you want to replace the backing paper, simply use one screw to open the panel. For signal input, it's designed for analog signals, but you can also use digital signals. Just send a PWM signal from a 5V logic microcontroller, and make sure the frequency is 1KHz or faster. When connecting wires at the back, you have two options. You can wrap the wire around the bolt and use nuts to keep it in place, or use alligator clips. As for maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or humidity. If you notice any issues, check the connections first.
