 No, the Kniwwelino has no battery included. This would have considerably increased the size and the price. The easiest is to attach it to a USB plug (on the computer, a USB hub, or a power bank) via a micro USB cable. There is also the possibility to attach a battery holder for 3 AA/AAA batteries (requires soldering). For more information consult this section [[en:introduction#the_power_source|Power Source]].\\ No, the Kniwwelino has no battery included.

-=== Why does it take so much time to transfer the code to my Kniwwelino? === 
-When you press the upload button, the code is first uploaded to our servers and compiled (5 seconds), then send to the Kniwwelino (about 25 seconds), and then the Kniwwelino reboots and connects to the Wifi (about 3-5 seconds). If you are uploading a code for the first time, the first step might take longer (up to 30 seconds). \\

-=== How can I save my programs? === 
-You can save your program on your hard disk by making use of the ''open'' and ''save'' buttons accessible from the menu.

 +=== I press button A (or B) on the start of Kniwwelino, but it just keeps running the demo program ===
 +Make sure to press **and hold** button A (or B), then plug the board and release the button only when the pattern shows up (or the WiFi mode is active). In case you see the program running, it did not succeed, and you have to repeat the procedure again.

-Alternatively, you can reset the Kniwwelino by uploading a new code onto it. Create a new (simple) program with Kniwwelino Blockly (online or desktop version) or the Arduino IDE (based on Kniwwelino Lib) and transfer it to Kniwwelino. After that you should be able to see the welcome message and use the Wifi connection tool. \\+For more information on how to use the Kniwwelino Flashtool see [[en:preparation:flashtoolinstall|]] and [[en:preparation:flashtoolreset|]].
