Experiment class is in tandem with graduation research. When I’d been getting of adding sensors for controlling function by ultrasonic sensor, the problem was happened caused by incorrect wiring. Pro Micro was missed on PC serial port because of its hardware trouble.
Pushing reset pin is one of the solver. But it was not effective, nothing was getting well. I thought that it has an another trouble, like software’s one.
Pro Micro is compatible with Arduino Leonardo, not UNO, a little complexed. Wiring like these.
After completion of infrared sensor RC car, as preparing before tranferring Bluetooth modules system, I need to understand specification of Bluetooth module and, how’s it work.
done.
The project first section is completed.
Having done:
On the previous Motor Driver works, too upper current make it bad connection. Appear noise, and burned IC. Calculating exact value is important for circuit working correct and prevent malfunction.
I am succeed at circuit minimization, using UNO to Pro Micro. On the next class, we can ride it on MECHA KAME base. [Source]↓
Regarding previous contrains, we can only drive the motor mono-direction. It means not tobe bidirectional control. We have to some missions about not to use motor drive IC, so the ideal thinking of transistor discrete circuit is needed for project of experiment class.
Because of their some restriction, trying some applied circuits are desirable.
To implement H-Bridge Circuits are required two pairs of NPN and PNP transistors numbered-pair.[circuit picture]↓
At first, combining that circuit and coding one motor control are begun, but it just errored by component’s malfunction. That also should be expected, they were picked up from outmoded rc toy.
Proceed to implement any other function.
Infrared Remote Controlled car was worked well, so if we can set resister that considerate upper current, the motion are same as bidirection.
The next visions are these.
