Re: Voltage to Current board

Thank you all for your responses. I want to use DC motor. I want to balance a ball on a plate, and for that I need to control torque. You may say that a lot of people built that system and didn't need to control torque. My controller is different(It's a nonlinear controller). All those people used P...

Voltage to Current board

Hello I am working with Raspberry PI 3, and I am using two DC motors. DC motors need to be run at a specific torque, and torque is proportional to current. I cannot send current to DC motors from Raspberry PI directly. I already have all equations of DC motors and how to convert torque to current. I...

wiringPi PWM problem?

Hello I am working on a project. I want to build ball-on-beam system, and I have mechanical setup of the system. The problem is that I think encoder reading has a problem. Sometimes I send zero PWM, but encoder is counting. When I print counter, it shows that it is counting(with 0 PWM). I use wiring...
