Logic gates are basic elements of digital integrated circuits.They act like the logical operators. The main logic gates are AND, NOT, OR. Usually logic gates have two inputs and one output, except the NOT gate, which has one input. The output of an AND...
The Voltage Divider The AtTiny167 didn't have enough pins for two controllers so, for each port, I made a voltage divider out of three resistors which allows two digital inputs to be read by one analogue GPIO pin. You can see the circuit working...
Full Overview Continuum is a light art display that is continuously in motion, with options to move quickly, slowly, or incredibly slow. The RGB LEDs in the display are updated 240 times per second, with unique colors calculated each update. A slider...

Hello Here is the story of building a 4m x 1.60 m led panel 123 *48 leds I started first with smaller boards 20*15 then 20*30 just to have an idea of what it possible. And use couple of controllers (Arduino uno, due, mini, pro, esp8266,esp32) it...
At the beginning of the new year, robot/Smart Car hobbyists and students (like all of you) about engineering, science and technology are busy with preparing for the robot competitions now. It's the great time to show the world your imagination and potential...
My father likes to create models of all his past vehicles (mostly boats), then he asks me to turn them into running remote control models. He now has a sail boat, 2 speed boats and recently presented me with a canal boat to electrify. I did create...
Izhikevich Neural Model:The Neuron Eugene Izhikevich developed a simple, semiempirical, model of cortical neurons. The properties of each neuron are controlled by 4 parameters, plus a constant current input. His web site includes matlab programs and...
