DIY Arduino electric screwdriver project

Makers and hobbyists searching for a new Arduino project to keep them busy this weekend may be interested in a 3D printed DIY Arduino electric screwdriver created by “Progress Thailand”. The DIY electric screwdriver is fitted with a 9 g Micro server which has been modified for continuous rotation and connected to an Arduino Nano. As you can see from the image above the electronics have then been housed in a ...

CO2, temperature and humidity monitor

CO2 Monitoring is mandatory in many workplaces and it affects two of my clients directly in Barrel Halls where wine is stored and aged in temperature and environmentally controlled areas. The table below shows the affects of various concentrations in the air. 250-350ppm Normal background concentration in outdoor ambient air 350-1,000ppm Concentrations typical of occupied indoor spaces with good air exchange ...

How to build a simple Arduino shutter speed tester – by Ethan Moses

I’ve been stuck in my house filling orders for my Kickstarter campaign for the CAMERADACTYL 4×5 Field Camera, mostly just babysitting printers, changing filaments and adjusting extruders every few hours. This has left me with some rare time for tinkering. Recently I built a cheap, quick and dirty tool to calibrate a project that I was working on. I was adding manual shutter speed adjustment to my Yashica El ...

ARTISTIC IMAGES MADE WITH WATER LENS

It’s said that beauty and art can be found anywhere, as long as you look for it. The latest art project from [dmitry] both looks in unassuming places for that beauty, and projects what it sees for everyone to view. Like most of his projects, it’s able to produce its artwork in a very unconventional way. This particular project uses water as a lens, and by heating and cooling the water it produces a changing ...

Interfacing Flame Sensor with Arduino to Build a Fire Alarm System

In this article we interface Flame Sensor with Arduino and learn all the steps to build Fire Alarm System by using Arduino and flame sensor. Flame sensor module has photodiode to detect the light and op-amp to control the sensitivity. It is used to detect fire and provide HIGH signal upon the detection. Arduino reads the signal and provides alert by turning on buzzer and LED. Flame sensor used here is an IR ...

Driving 14-segment displays with the MAX6954

Abstract: This article is how-to guide, intended as a quick learning aid for engineers considering using the MAX6954 to drive 14-segment monocolor LEDs. The MAX6954 is a versatile display driver, capable of controlling a mix of discrete, 7-segment, 14-segment, and 16-segment LED displays through a serial interface. This application note shows a typical application and configuration for driving eight mono-co ...

Cheap Arduino Serial Terminal

How about a cheap serial terminal for less than a fiver all-in? In a previous blog entry I’ve been working on more developments for the increasingly powerful home control system using an Arduino as a kind of universal I2c peripheral to the ESP8266. The reason for that is just the vast range of driver software our there and the fact that from China you can get an Arduino-Nano-type-board for under £2. There a ...

DIY Arduino Motor Driver Shield

In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling them. Components Required Motor Driver IC L293D -2 ...
