![]() That was really helpful! I did your tests and it turns out the positive screw block works, but the negative one does not for some reason (when the positive wire is connected to the adapter and the negative wire is connected directly to the battery, it works. If the connector failed any of the test's it is bad. Next and last connect the 2 wires to the screws + and - and see that the light doesn't light. at any rate put one wire in the hole in the end of the "Barrel " connector, the light should light. Now take 2 20 cm lengthe of wire and strip 10 mm off of each end (4 ends/2 wires) connect one wire to the open (- or the side of the LED with the little "Flat") end and the other wire to the - end of the battery (the male or bigger of the two terminals) when you touch the two open ends of the 2 wires together the LED should light. ![]() Connect it to the open end of the 1K resistor. The LED has one wire longer than the other, that lead is usually always the + Led connection. Do I need some sort of electronic part in my circuit to run the servo off the battery and am wiring everything up right?Īlso, since I can't seem to get this stupid battery to work, is there another part that I can use to power 5 or 6 servos via my Arduino's 5V pin? I think I read somewhere about something like that.ĭo you have a DMM? if not a 1K resistor and an LED and some hookup wire? connect the resistor to the + end of a 9V battery (its the female or the bigger of the two connectors. The documentation for the servo says it can handle up to 6 volts, but works best at 5 volts. I'm pretty sure the battery pack I'm using supplies 6 volts (it has four AA batteries). I'm not using resistors or anything else other than that one servo and normal wires. Whenever I've tried - including this time with the adapter - I've connected the positive battery wire to the positive rail and the negative battery wire to the negative rail and wired everything else up accordingly. Is there a specific way of connecting batteries to breadboards? I can't remember successfully wiring up a battery, I've always just used the Arduino 5 volt pin. ![]() It's exactly the same size as the Arduino's and the connection is snug. Okay, well the barrel-jack pin is definitely the right size. replaced all the batteries in the battery pack checked to make sure the adapter's wires are plugged into the correct rails the servo DOES recieve power What I've tried: I try the exact same thing, but with the 5V and GND pins on my arduino I plug it into a Female DC power adapter Does anyone know what the problem might be? I'll attach some pictures of what I'm talking about. To my understanding you unscrew them slightly, push the end of the wire in until it reaches the back, and screw the screws back in tight enough to hold the wires, but not tight enough to cut them. I've never used screw block terminals before, so I'm not sure if I'm using it right. I tried rearranging wires on the breadboard several times and I hooked up my 5V and ground pins in the place of the DC Power Adapter wires and the circuit worked and my servo received power. I know this sounds like a simple wiring problem, but I know for sure the wiring is correct, at least to my knowledge of electronics. I know the battery pack works when I plug it into my arduino, it turns on, but when I plug it into the DC power adapter and wire that to my breadboard to power the servo, it doesn't work. I've been trying to use it with a breadboard and a 6 volt battery pack with four AA batteries to power a Standard Servo ( Standard servo - TowerPro SG-5010 : ID 155 : $12.00 : Adafruit Industries, Unique & fun DIY electronics and kits). I recently purchased a Female DC power adapter with screw block terminals (this is the exact product: Female DC Power adapter - 2.1mm jack to screw terminal block : ID 368 : $2.00 : Adafruit Industries, Unique & fun DIY electronics and kits).
