L298 stepper motor controller
Stepper motors are a very powerful, yet accurate type of motor. The ability to ‘step’ through motion instead of to run uncontrollably like dc motors do is a great advantage. This write-up shows you...

DC motor speed controller
This motor speed controller powered by the PIC16F873 detects and controls the rotational speed of the motor. When lower than the specification speed, it increases a control electric current. When...

DC motor speed control using PWM
The PWM frequency is about 10 kHz and does not make a noise in the motor. The 5 K Ohm potentiometer is connected to ADC input channel 0 and is converted to 1024 (10 bit) value, this value is applied...

Braitenberg robot with Arduino
Here is a good project for those who want to start with robotics. Fairly simple and if you are using a breadboard there is no soldering involved. It is a vehicle that follows a light source using two...

Implementing a Brushless DC Motor Controller
Inside of a SONY brushless dc motor For an upcoming project I’ll be needing a brushless dc motor controller so I had to choose between purchasing one (more than 4 actually) and adapt my system around...
