Arduino, HM-10 And App Inventor 2: Adding A Slider

This post continues the Arduino, HM-10 and App Inventor 2 guide. A few people asked about adding a slider so here it is. Please beware; this is not a basic guide for using a slider in App Inventor 2. I am adding a slider to an existing app and have certain things (semi advanced) that I want to achieve.

I created an MIT app inventor app and am trying to use the slider function on the app to control the motor speed. But when I open the serial monitor to see what is coming in from the HC05 that I have connected to the RX and TX pins on the arduino as well as the 5v and GND some gibberish comes up. I have attached an image of what the serial monitor produces and my MIT app inventor blocks. I have read that alot of people get this issue via baud rate but mine has already been changed to 34800.Any help is greatly appreciated in solving this issue.Here's the code: 2ff7e9595c
