The circuit Diagram for the Controlling Stepper Motor using Potentiometer and Arduino is shown above. We have used the 28BYJ-48 Stepper motor and the ULN2003 Driver module. To energise the four coils of the stepper motor we are using the digital pins 8,9,10 and 11. The driver module is ...
Arduino is connected to PC through the USB cable. We can send the command to PC on the serial monitor. We can change the speed of motor from 0 to 9. When 0 is sent over the Serial Monitor, the motor runs at minimum speed (that is zero). When the speed is varied from 1 to 9,...
I’m going to build an Arduino ATmega1284P circuit on a breadboard, burn a bootloader, and upload sketches to it, all using the Arduino 1.0 IDE. This will all go better if you have done it once first with a regular ATmega328P. Doing these things on that chip is well-documented, and...

In this tutorial we are going to interface a DC motor to Arduino UNO and control it's speed using PWM (Pulse Width Modulation) concept. This feature is enabled in UNO to get variable voltage over constant voltage. The method of PWM is explained here; consider a simple circuit as shown ...
NOTE: Make sure the power supply from external circuit is disconnected before proceeding; we are going to power ATmega328P from arduino board. Diagram: Select “Tools” > “Board”> “Arduino/Genuino UNO” Plug the arduino to your PC and select right port for your arduino (vary computer ...
The correct circuit for driving an LED strip with Arduino is therefore as follows: Where VCC is obviously the Arduino output (digital or analog) and X1 represents my LED strip (or motor or any other dimmable equipment at 12V). Q1 is a TIP120, but any NPN or darlington NPN is fine, as...
it was small, but I had soldered to the tiny circle of copper and handling this circuit placed too much stress on this connection. The wire I added ripped off the copper pad, leaving non-conductive (and non-useful) bare circuit board material behind. This isnotgood. I needa backup ...
For the video and audio output he created an add-on board for the Uno that creates a composite signal using two resistors, along with an audio driver circuit and control inputs either from the onboard buttons or from a NES controller. Audio can be sent either over the composite output or...
It is often useful for both the Instructor and the student to analyse the signals and waveforms used in the circuit. With Visual Designer this doesn't require any hardware and works directly on the simulating schematic either on the PC or on the projector in the classroom.Simply place and wi...
