“In this Post, I will show you how you can make your own 5V to 3.3V logic converter for connecting 5V sensors to new Arduino Boards and Raspberry Pi. Why do we need a Logic Level Converter IC? Most …
“This device allows you to send any message using morse code. (you don’t need to know morse code for this projects) In short: you send morse code with ESP8266 or Arduino and receive it with a smartphone’s camera …
“A long time ago, 7400 logic was all that was available, but having only 7400 logic means designs can get big and difficult, but making a custom logic IC was expensive and hardly a possibility. A few companies started making …
“Using 14 panels with ISSI IS31FL3733 I2C matrix controllers, this artwork can show 8-bit grayscale on 2,688 individual LED segments. This artwork has a large, handmade array of small, numeric displays that show a sequence of numbers. Using its …
“Unique tool and desktop or wind sill trinket to alert when the ISS is overhead. The International Space Station (ISS) has been up and running since 2000. Since that time, we have always had humans living in space. (Pretty Awesome …
“A Two-Degree-Of-Freedom Ball Balancing PID Controller In this project, we implemented a two-degree-of-freedom ball balancing platform using a resistive touchscreen, two servo motors, and PID control. We used a PIC32 microcontroller to read position data from the touchscreen and drive …
“Brushless electric motor (BLDC motors) are synchronous motors that are powered by a DC electric source via an integrated inverter/switching power supply, which produces an AC electric signal to drive the motor. Hall sensored motors uses hall effect sensors …
“Easily pick colors from physical objects with this Arduino based RGB color picker, enabling you to recreate the colors you see in real life objects on your pc or mobile phone. Simply push a button to scan the color of …
“In the modern age, being able to interface efficiently with a computer is necessary in order to complete many everyday tasks. For individuals lacking manual dexterity, the task of using standard computer peripherals can prove to be nearly impossible. As …
