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- […]
The following instructable describes a easy to build and inexpensive device to perform pressure measurements and demonstrate Boyle’s law, using the micro:bit in combination with the BMP280 pressure/temperature sensor. Whereas this syringe/pressure sensor combination has already been described in one of my previous instructables, the combination with the micro:bit is offering new opportunities, e.g. for class […]
Wireless power transfer systems are well on their way to replacing conventional wired charging. Ranging from tiny biomedical implants all the way to wirelessly recharging huge electric vehicles. An integral part of the research on wireless power is minimizing the magnetic field density. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides scientific advice and […]
Honestly, how many people have been in this scenario (leave a yes or no in the comments) : It is 2:30 in the morning and you wake up with a need to do something whatever that may be (bathroom, forgotten homework assignment, project due in 5 or 6 hours, etc.) it takes you 5-10 minutes […]
