The Mid Autumn Festival Night

I used a 2 port usb portable charger to give power to the 2 lanterns, ( put inside the white plastic bag , linked up with blue usb extension cable ), the power usage is incredible small because only used 10-20% for 5-6 hours non-stop light up .

I also prepared some hot air balloon lantern, i wrote up a candle light effect with arduino then powered up with lithium battery, the top of the balloon is lighted up by RGB LEDs, without BLE module. The battery perform extremely well and still remain bright all night. This hot air balloon is so famous that many people around take a picture in front of it.
