All of that and more are discussed in this previous tutorial about DC motor control with L293D driver. Check it out and come back to resume developing our DC motor driver library for STM32 microcontrollers.

This example will show how to model a DC motor's speed using different approaches in Collimator. The three approaches involve simulating diagrams from a differential equation, a transfer function, and a state variable model. Then, we will design and simulate a PID controller for the DC motor speed.

We can order the PCB from JLCPCB which are the PCB fabrication service of EasyEDA, and also they are the sponsor of this video.

So if i were to modify the motor speed control using arduino to run 2x motors (in parallel) that ran @ 12v .4A on one pwm channel, what would the capacitor rating and transistor rating have to be? would an NTE293 npn transistor be sufficent? And if so, does R1 have to be changed at all?

type DC Motors (permanent magnet types), our range does not apply to brushless which uses a completely different method to control motor speed than a brushed motor does!

There are different types of speed control of dc motor. Let us discuss, how the speed can be controlled with the above parameters.

Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is no base current, the transistor is driven into cutoff region of operation and therefore there is no collector current. In this case there is no current flowing through the DC motor.

Much of this code, at least the part in the loop() function, has been taken from the sketch in Lecture 11. It generates the ping pulse that is emitted by the sensor, and then calculates the distance of an object from the time it takes for the echo to return.

The purpose of a motor speed controller is to take a signal representing speed from some sort of adjustable control (for example a Potentiometer or a Hall effect device) and to drive a motor at that speed.

Time to do the wiring. You can remove the potentiometer to the circuit from Project 2 and replace it with the ultrasonic distance sensor. I am copying here the complete instructions so that you don't have to jump back and forth between the two articles.

Settings can be one digit at a time or fast sweep. The OMDC-MD series speed control settings are exact and repeatable. It will precisely control speed to ±1/2 RPM of set speed, long term. No calibrations of the control are necessary.

We can control the speed of the DC motor by controlling the input voltage of the motor. For that purpose we can use PWM, or pulse width modulation.

It can supply up to 1A of current and voltages from 4.5V to 36V. This means the L293D motor driver is ideal for building multi-wheel robot platforms. Here’s a diagram of the L293D showing how to connect the motors:
