Traffic Control with Walabot

Smart traffic control for more livable cities. Story Abstract Traffic light control hasn't changed much in the last decades. Since IT changes everything, it's time to transform the traditional traffic control systems to smart ones that adapt and react to their environment. The story I was experimenting with Walabot, trying to make something with cats, because... Well because cats are fun. But then this happ ...

Calendar- Time – Humidity and Temperature Arduino LCD display

The power saving mode here is what sets this Instructable apart from other examples showing day of the week, month, day of the month, time, humidity, and temperature. It is this capability that allows this project to be run from a battery, without the requirement for a "wall wart". I had posted an earlier Instructable, Humidity and Temperature LCD Display with Power Saving Mode: Minimal parts, Fun, Quick, a ...

Circuit delivers constant power to a load

If you have a load with a variable or poorly specified resistance and want to regulate the power applied to it (a heater for example), merely controlling the voltage or current will not work, as in both cases the power P = I2R = V2/R depends on R. Instead, let us generate pulses with constant energy Epulse, independent of the resistance of the load RL. Then by changing the frequency f of the pulses we can c ...

External Hardware Monitor

Hi guys! Today I will show you how create an external hardware monitor with any Arduino board(in my case a pro micro board), a Nokia 5110 LCD and some VB programming! Let's get started! ps. Sorry for my bad english Step 1: What Is the Aim? The aim of this project is for monitoring pc hardware while you're in game. There are other many system to do that, like afterburner ingame overlay, but for me is too cum ...

Analog Devices – Arduino shield for critical, accurate, robust and non-contact turbidity measurements (EVAL-CN0409-ARDZ)

Analog Devices EVAL-CN0409-ARDZ Arduino Shield uses the ADPD105 photometric front end and a network of 860nm Infrared emitters and silicon PIN photodiodes to produce a water turbidity measurement system. The system can measure low to high water turbidity levels ranging from 0FTU to 1000FTU. The IR LED, and photodiode network is managed in such a way that it can carry two of the most recognised turbidity mea ...

Wi-fi browser controlled servomotors

This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser (Firefox, for instance). This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was designed with HTML and jQuery. Miguel's tutoria ...

ARDUINO NITROX ANALYZER FOR THE SUBMARINE HACKER

For Hackaday readers who don’t spend their free time underwater, nitrox is a blend of nitrogen and oxygen that’s popular with scuba divers. Compared to atmospheric air, nitrox has a higher concentration of oxygen; which not only allows divers to spend more time underwater but also reduces the risk of decompression sickness. Of course when fiddling with the ratio of gases you breathe there’s a not inconseque ...

Review: Siglent SDS 2304X oscilloscope

I’ve had a Siglent SDS1102CML two channel 100 MHz bench scope here for the last two years. I demand a lot from my test equipment so had low expectations when it arrived. After all, how good can a $359 unit be? Turns out, quite a good for the price. I reviewed it here. But the screen is smaller than most modern pro scopes with lower resolution than many would like. And 100 MHz just doesn’t cut it for a lot o ...
