I am a complete novice with Arduino stuff. I have a S4A EDU controller that I have got plugged into a Windows 10 desktop.
I have selected the board type as Arduino Uno and COM3. In device manager it says Silicon Labs CP210x USB to UART Bridge (COM3) and I have verified that this disappears if I unplug the board from the computer. It says I have the most up to date drivers for this device. I am using Arduino 1.6.8.
The board has a constantly flashing blue light and a continuous red light regardless of whether the board is switched on or not.
When I upload Blink it takes a few minutes before saying Problem uploading to board. The detail says not in sync and programmer not responding.
Help please.
