Modernization
Hello all.. Whats up...
Especially for them who assembled...
I want give my practice for modernization this aggregate...
1.
Long time I attempted regulate speed drive chassis, and then I changed motors in chassis...
DC motors from printer-scanner will you see at photo (Hewlett Packard CB605-60043 Scanner Drive DC Motor) or (hp M1130 M1132 M1136 м 1130 1132 1136 Q3434-60238).
Motor RPM speed can regulate in string arduino code...
....
//for motors RPM speed
(allowed change value diapazon from about 100-250 at this You change voltage to motors!... see voltage diapazon for motors)
byte max_skor_lev = 250; ( for left motor)
byte max_skor_prav = 246; ( for right motor)
//---------------------------------

At the photo You can see.. how was connected mosfet IRF520 and small motor...
a) White wire get positive (+) signal from L298N module to mosfet IRF520 (where writed SIG, see at photo...)
b) Two green wires this is (+) and (-) to small motor...
c) Red & black wires this is 12v DC power for mosfet module...
P.S. Small motors will rotate when chassis will go forvard and will stop when shassis go to back or not move.

When Your device want not work with BT module.....
1. Check.. after conection Android-device at the BT module LED must light constantly...
2. Check.. How You connected wires to BT module from PRO Mini...
Must be... (+) to (+); (GND) to (GND) ; (at the PRO Mini must be (RX)) to (at the BT module must be (TX))... I used only this contacts...
P.S. You should use BT module what recomended instruction PART1...
