Control servo motors with potentiometers and Arduino

Hi there. This is my first instructable, so I hope you will be patient with me if I make any mistakes setting it up.It is written for beginners like myself, so the more advanced among you can skip a lot of this and just get to wiring it up. The goal I set myself was to be able to control the robot shown in this web site: http://bocabearingsworkshop.blogspot.co.id/2015/08... I needed to be able to control 3 ...

Tiny Message Board

We will make a tiny connected message board with a 0.96" OLED display that can be controlled from your phone. We will use the IFTTT "DO" app to set and clear the reminder so that no extra hardware will be required besides the OLED display. In addition to the reminder, our tiny message board can display 3 other lines, which we will use to display the daily weather temperature forecast and a surf report, whic ...

Arduino Display for Liquid Flow Sensors

Overview This project was done for a Friend Of a Friend. He needs to monitor water flow rate and quantity for his solar heating projects. He is mainly interested in this two inch sensor but also sent along a small plastic hose bib type similar to the Adafruit 828. Both of these sensors are turbine types, water flow spins a plastic wheel which magnetically triggers a pulse output proportional to the speed at ...

The Pendulum Clock

If you've ever rode the Link Light Rail in Seattle to the airport, you may have glanced out of the window while traveling through a tunnel and seen playing cards illuminated on the walls. These images are not made from two dimensional screens. Each display is just a row of lights that changes rapidly as the train drives by, giving the illusion of a two-dimensional picture. The University Street station also ...

Home Improvement DIY: WiFi Gas Detector with Text Alerts

Hey guys, back with another little project that I’ve been fiddling with for the past week. With kids around, every parent is thinking how to make their home safer for the little ones and for everybody in general. One of the most dangerous thing in the house can be the stove and since we have a gas-powered one, I always wondered why there are no simple gas detectors that can be used around the stove, just to ...

Simple, Cheap Motor Controller

I've used this simple circuit several times to drive motors (like in my Stair Climbing robot) as well as solenoids. I originally picked it up from this instructable which is focused on controlling a solenoid. I wanted to isolate this circuit in its own Instructable as a motor driver so I could easily reference it from other future instructables and also provide example code to show how to use it in this man ...
