I connected a circuit and nothing is happening. Is the battery dead?
Your battery block is rechargeable! If your circuit is not working, the battery block may be shorted or discharged.
First, to see if the battery is shorted, try turning the switch on the battery to the off position (left side if the battery block's text is right side up), waiting about 10 seconds and then turning it back on. There is a red LED on the battery that should be on when the battery block is on. For more of an explanation on this, please try doing the "Short Circuit" project in the LightUp Learning app.
If the red light on the battery block still does not turn on, the battery needs to be charged. You can recharge it with the provided USB cable by connecting the cable to the battery block and a USB wall adapter or laptop USB port. The orange charging light on the battery block will turn on when it is charging, and the green light will turn on when charging is complete.
