We know the analog potentiometer , is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider . MCP41100 an Arduino Controlled Potentiometer: 1)volume controls on audio equipment. 2) Control the amplifier Gain and offset . 3) Transducer ” displacement transducers “. and many Other application , But did you you want to …
L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context – be it a server, phone, router or other monitorable device. The visual transformations represent various characteristics of these entities, such as packets …

This is a project in attempting to improve it predecessor “Freeform Arduino” by putting it in an enclosure and having it serve the similar purposes as “Palm Arduino Kit” and “Palm Arduino II” which I can carry it in my pocket and be available to use, and to connect to easy available power source specifically …
Here’s a small, quick project you can do with an arduino, the EMF Detector! Step 1: Circut All you need for this project is 10- 330 ohm resistors 10- LED’s 1-3.3m resistor 1-Solid core wire (this will serve as the probe) breadboard, wires, battery & connector for arduino to make it portable Step 2: Hooking …
In many cases switches are just switches. They directly control the flow of electricity to an appliance, flashlight or mains-voltage lamp. An example of this is the switch on the wall in your living room. In many cases nowadays however, switches are digital sensors, meaning that instead of directly controlling a high-powered device, they are …

Introduction: Our main goal with the Tiich system is to design a teaching aid/tool which would replace the conventional whiteboard in a classroom environment. We want our system to be used as an electronic based white board, having all the written information easily be saved and submitted to all the students in the classroom. We also …

Took me a little while to get started but I’ve managed to wire 2 PIR infrared sensors with an Arduino to sense motion either on the left or on the right side. The result will trigger an LED to represent each PIR sensor then I also added in a servo to be controlled – so it turns left when triggered by the left sensor …

Did you know? You can make pencil drawings reactive to touch for use with your projects! It’s really easy, and gives you a lot of flexibility in making interfaces for whatever microcontroller project you’re making. I put this together as part of my UnoJoy project, where we’re using the Arduino as a platform from which …

Analog sensors produce an analog (continuous) voltage that typically varies from 0 to 5 volts. They have three wires – ground, power, and signal (typically red, black, and white, respectively). Examples shown below include: Potentiometers Proximity Accelerometers Ribbon Bend Pressure Light Temperature Sound Multi-touch Touch Other Potentiometers Potentiometers typically measure rotation or linear travel, and …
