The original idea was to create a library that simplify the use of IC 74HC595 between Arduino and other hardware. In this Instructable I will share this to you using as example the control of a 16×2 LCD. The example will show on the LCD the seconds that has passed since Arduino was restarted. I […]
This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can be powered from a standard 9V PP3/6F22 battery, or […]
Electronic Brick, Waterproof and other Versions NOTE: There are different-appearing versions but they work the same. This is an electronic thermometer which has high accuracy over a wide range (accurate to ±0.5°C over the range of -10°C to +85°C) (Workable from -55°C to +125°C). You can locate these thermometer chips up to 100M away from […]
If you are contemplating building your own machine, then you probably already know a good bit about how pinball machines work. It’s basically series of electro-mechanical events where a steel ball activates a switch, which in turn fires a solenoid that drives a mechanism, sending the ball off in some other direction where it most likely hits another switch, and so […]
After experimenting with Arduino and Processing serial communication i wanted to do something cool. I had some RGB LEDs lying around so i thought about making something with them. I ended up with a strobe/lamp controlled by a Processing sketch that receives the commands from a Hercules DJ Control Steel MIDI controller. It uses 2 […]
In this instructable, I will show you how to make a simple toy that combination of the LEDs flash and Theremin. We’re gonna using some basic electronics built on top of an Arduino. The basic idea of 7 Segment LED Display was from Enjoying Electronics. The original Enjoying Electronics article is here, you can get […]
I recently got my shipment of 10 buzzers I ordered about a month ago, so as soon as I got them I was eager to make something fun with them, so I looked around a bit and searched for what to do with them, and by spending some time on www.arduino,cc and posting lots of […]
In this Arduino-based project, we will build a lamp with multiple light displays: color sequencer, dimming light, color chaser, firelight – all selected by a touch bar on the circuit board. All the functions are done in software, including the touch sensor, which is a unique feature. Step 1: What is needed? We will be […]
I’ve been browsing this forum and the internet now for a couple of days and what I thought would be an easy side project turned into a (for me) quite complicated matter. I’m planning to build a mood light that consists of 12 common cathode rgb LEDs with each colour being controlled by an Arduino’s […]
Temperature and humidity measurement are always a nice addition to hobbyist projects. In my previous post, I’ve discussed the DHT11 sensor, which is capable of measuring both temperature and humidity. They are digital sensor and provide calibrated outputs with temperature and relative humidity. I’ve also demonstrated how to interface with Arduino and display it on […]
