n this Instructable we will simulate an Toll Booth Gate by using a manual Push Button to open and close the gate. How Does It Work? When the vehicle comes in front of the gate, the push button is pressed & the gate is opened, this is done by sending a command via microcontroller to the servo to open the gate

We have build car using many transmission technologies. But what about a WiFi Controlled Car? Actually speaking..Wifi is till now the most promising technology and engineers are using that tech to improve it more and more. This tech is most popular today and will remain for decades.Low power WiFi have also been developed.So let us
WiFi Car Using NodeMCU Continue Reading
This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and

When I say simple, I don’t mean use a speed control. But control the motor directly without any external circuitry. Here’s how: How this came about: I recently was working on an instructable about charlieplexing with an arduino. And I was wondering if the same principle would work with motors to some extent. So I came

This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino. Next, it’s onto 180 degree servo motors, which we will power on

This instructable will show you show to build an Arduino shield which can be used to control 3 servos and 1 stepper motor using 4 potentiometers. You will need: access to a laser printer/cnc router/etching chemicals 7 x 3 pin 3.5mm terminal blocks 2 x 2 pin 3.5mm terminal blocks 2 x 8 pin stackable
Arduino stepper motor and servos shield Continue Reading
There are a lot of ways that you can activate an electronic lock. You can use passwords, radio signals, or even voice commands. In this project, I am going to show you how to make a lock box that opens and closes based on color recognition. With a color recognition lock, anything can be a

Hey! This I’ble is now out of date! I made an updated version which you can read here! Hope you find it fun and useful! ~~~~~ Thus far, I’ve shown you how to create wheels out of household items, severalmotorizedchassis out of cardboard, and a couple of simple and effective light sensors. Now, one of

This is a tutorial for making the Tidal Clock. The clock shows the ebb and flow between high and low tide by a rising and falling water level. It consists of an airtight acrylic container that has a front visible chamber and a back hidden chamber. A volume rotates through the back chamber, displacing the
I have been trying to get my hands on a laser cutter for some time but they always seem out of reach. All the great things that can be done with a real laser cutter tickle the imagination. I feel it’s time to share my latest project – a low cost laser engraver,. The workspace
