“A small and portable Temperature, humidity, and light monitor that can be placed instantly anytime. Background Story A problem that I want to solve by creating this project is the building maintenance system at my workplace still need to check manually and we have more than 30 rooms that need to be check twice a day by one or two …

“This is my version of a small self-balancing robot. A have tried to keep the design as simple and cheap as possible, without compromising performance. The robot uses two NEMA14 stepper motors and the electronics consists of a single Arduino Pro Micro and a MPU-6050 gyro/accelerometer breakout board. Two A4988 stepper drivers are used to drive the motors …

“My business card is an ATtiny85 dev board the size of a credit card. Types out my contact info when a capacitive touch sensor is activated. Primarily designed to be used a Business Card/Resume/Portfolio, it is an ATtiny85 dev board in a credit card sized form factor. PCB files in Fritzing, so easy anyone can modify them for …

“Basically this was our college project and we had less time to complete this project because of that we forgot to take pictures of some steps. I also designed a code using which one can control this robotic hand using gesture and voice at a same time but due to lack of time we were not able to implement it …

“In this project we will have a closer look at a common buck/boost converter and create a small, additional circuit that adds a current limit feature to it. With it, the buck/boost converter can be used just like a variable lab bench power supply. Let’s get started!”

“Hello everyone, recently I started working on some robotics related projects using Arduino. But I didn’t have a proper base to work on, the end result didn’t look great and only thing I could see is all my components entangled in wires. Trouble shooting any error used to take like forever and wiring things again and again was …

“The PIDDYBOT is a small Open Source balancing robot with the aim of teaching PID controls using a “hands on” concept. Anyone can play with the PIDDYBOT and start to develop an understanding of what the P, I, and D terms within the PID loop do, even if that person has no concept of the math behind the control itself …

” A SIMPLE 444 LED CUBE USING ARDUINO NANO”

“This alarm clock is an attempt to get our toddler to stay quiet in the morning while we try to continue sleeping. My wife asked me, “do you mind if I spend $27 on a toddler alarm clock?” When I figured out what such an alarm clock does, I decided I could make that from parts I had in my …

“Hello everyone! . In this instructable I’m going to show you how I built my 4X4X4 Led Cube. For this cube I used Blue LEDS and NPN Transistors to drive ground signals to the layers of the cube to make coding easier. I hope you are all going to like this instructable.”
