Can lantern batteries be recharged Triple Helix 2020 cinewoop from Vtech bt266342 rechargeable aaa cordless phone battery. #define oldLED 9 //Set the old/dead led to pin 9 The voltage of this battery is not fixed, with the lowest being 3.2v and the highest being 3.7v. #define okLED 10 //Set the okay led to pin 10 Simple battery testing program #define newLED 11 //Set the new led to pin 11 The code that I used was an edited version of wcyoder's program, which is used to test more than one battery. When you're done it should look something like the schematics above. This will connect to the positive side of the battery we are testing.Ĭonnect another wire of around the same length to either the ground rail or the spare GND pin on the Arduino. Run a jumper from E12 to pin 11 on the ArduinoĬonnect a relatively long wire to pin A0 on the Arduino. Run a jumper from E8 to pin 10 on the Arduino Run a jumper from E4 to pin 9 on the Arduino Place the short leg of the third LED in E11 and the longer leg in E12īend resistors so the legs connect the GND rail to E3, E7, and E11 ![]() Place the short leg of the second LED in E7 and the longer leg in E8 Apps should not rapidly drain battery, generate excessive heat, or put unnecessary strain. Place the short leg of the first LED in E3 and the longer leg in E4 People need to know how to reach you with. Run a jumper from the GND pin to the negative side of rail. Run a jumper from the Arduino's 5v pin to the positive side of the rail on your board. One is for the more visual learners and the other is a more traditional pinout. Lay out all the components you'll be using in front of you. Start out with a clutter free and static free work station.
