This Instructable will show you how to make a Portable Digital Optical Tachometer using an Arduino Uno. This project is inspired from This instructable and is an enhanced version of it with an LCD display and a modified code. Instead of a slotted sensor , it has a reflection based sensor. So : 1. You […]
RC cars can be WiFi Cars…? RC cars are cool, but cheap RC cars have limited range and can only be controlled with the particular controller that was included with the car. I purchased a RC jeep, complete with 4 wheel drive, flexible suspension, and off-road tires for about 30 bucks. Not long after playing […]
Summary Students will learn how to construct a water Level Indicator/Controller that monitors the level of the overhead tank by constructing a circuit that will notify the user via SMS if the water supply to an area/home is initiated and indicate how high the water has risen when it reaches too high or too low. […]
Summary In this project, we will create a water level indicator with three levels inside a tank using an Arduino and a water sensor, as well as three LEDs and a buzzer to indicate when the tank is full. Objectives To understand how a water indicator works When the circuits indicate that the tank is […]
An unremarked casualty of Progress is the aneroid home barometer. These days, you might still be able to find examples in the homes of people over ninety, but millions more are in the dump, or on ebay. In truth, the old-school barometer didn’t help itself by being pretty much useless at its one job. Even […]
This instructable shows how to modify an inexpensive RC car so it can be controlled by an on-board microcontroller. You can program the controller to make the car do any number of driving patterns and stunts. Once you have the car being controlled from the on-board controller, you can add sensors for light and sound […]
This fun little project will allow you the trivial joy of letting a electronic network announce that you have rain! The AI controlled, tear eliciting price’d Tesla has been rumored to have sensors that awaken the windshield wipers at the onset of rain. Being in a fully glass-enclosed cabin you would think that the obviousness […]

This will explain how we re-purposed a hand drill to re-spool solder using a roboduino (arduino compatible), two servos, and a DIY encoder. While one could use TRIACs to play with the AC power going into the drill, just using a servo to control the throttle is simple and avoids the pesky high voltage. Hand drills […]
When I first got into the Arduino I went looking for audio projects. One of the first things I built was TobaTobias’ Auduino granular synth. I was so impressed I built a permanent unit in a heavy duty enclosure and incorporated it into my occasional sets and demos.. This simple project makes really impressive sounds- […]
