The project looks good 
Avoid this coding style though ...
Code:
If (b1 <= 255 And b1 >= 243) Then
timerN = 1
timerAc = 600
timerBc = 180
End If
If (b1 <= 242 And b1 >= 219) Then
timerN = 2
timerAc = 180
timerBc = 60
End If
If (b1 <= 218 And b1 >= 193) Then
timerN = 3
timerAc = 120
timerBc = 60
End If
Very inefficient. Suggest rethinking your schema using a "Select Case" structure. No need for the logical AND operator at all. Put your thinking cap on and you should be able to reduce the size of the code by half!
