    Homework Writing Machine

    I have made the machine as per guidelines.It works with Arduino Uno board, but I am getting an error. When I connect the CNC shield it does not accept the right COM but keeps shifting between 1 to 9 and does not work at all. Your help is necessary. Sudhish

    Balancing Instructable Robot

    For last two days I have been trying to understand the wire connections showed by you, but could not understand. In the description you have mentioned that the PIN connections from Motor driver to Arduino should be: IN 1 to 5, IN 2 to 7, IN 3 to 10 and PIN 4 to 12 and in the CODe it is PIN No. 3,4,12 and 13 respectively. I am confused. In short what I have done is like this: Motor Driver pin IN1, IN2, IN3 and IN4 connected to Arduino's PIN 3,4,12 and 13.Moreover, The Enable A and B (both) PINs I have connected to Analog pin A3. My Bot is not getting activated except I can see the PID values through Serial Monitor. I have set the values like: kp= 105.00, ki= 12.00 and kd= 5.00. Are these values the targeted values or I am supposed to redo something else.I saw lot of photos of the wiring,...

Are these values the targeted values or I am supposed to redo something else.I saw lot of photos of the wiring, at different- different stages and got confused. Can you spare for me a total (final) wiring diagram so that I can complete the project.
