| Feb 10, 2020 at 13:16 | comment | added | sdebarun | okay I shall add the picture once I am home but just give me an idea of how to check the battery. While I check the voltage with multimeter I get 3.8V steady. If the battery is not fully charged then shouldn't it drop the voltage? | |
| Feb 10, 2020 at 11:20 | comment | added | Peter Paul Kiefer | According to the linked tutorial, the power source is OK. Did you see the warning that, the GND must be connect before any other pin (especially the VCC). Otherwise the device could be destroyed. A working LED is no guaranty that the board is OK too. Most probably you destroyed the device or you made a mistake when connecting the device or the batteries lifetime is at its end or the battery is not fully loaded. You did not add a picture of your setup, so I can not help further with an eventually false connected setup. | |
