- **SSID:** TWANG_AP
- **Password:** esp32rocks
- **URL:** 192.168.4.1
- You can update these settings over wifi
- LED Brightness
- Audio Volume
- Joystick Deadzone (removes drift)
- Attack Threshold (twang sensitivity)
- Lives Per Level
**Coming Soon:**
- Wireless features
- ~~A wireless version of the serial port features of TWANG. I think the easiest way is to make it a Wifi access point with a simple web page interface. This allows control by any smartphone or computer with no client side work required.~~
![](http://www.buildlog.net/blog/wp-content/uploads/2018/03/20180328_122254.jpg)
Coming Soon:**
- Wireless features~~
- 2 Player features by linking controllers. TBD
- Digitized Audio
- Currently the port uses the same square wave tones of the the Arduino version.
