This is something I’ve already worked on but was never really happy with the result, mainly because the potentiometre that I used was of poor quality and hence non linear and “jumpy”… The problem is simple: I need to have a reliable and easy to use servo tester, that I can use to test/play with a […]
In a recent instructable Indigod0g described a mini weather station that works pretty well, using two Arduinos. Maybe not everyone wants to sacrifice 2 Arduinos to get humidity and temperature readings and I commented that it should be possible to do a similar function with two Attiny85’s. I guess talk is easy, so I better
Step 1: Connections First let’s connect the Nokia 5110 display. Remember that the LCD runs on 3.3V and although some people have connected it to 5V, it has worked but gave some weird effects, so I suggest connecting to the 3.3V output of the arduino. Next, the LIGHT pin on the LCD. It is the
The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: 9-28V, AC or DC – 2 separate heater control channels –

When you think about Samsung, the first products that come to mind are probably phones or televisions, not Maker-focused electronics. Today, with their announcement at Internet of Things World, Samsung has entered the Maker world with their ARTIK platform, an Arduino compatible family of devices targeted towards Internet of Things applications. Currently there are three

We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM on Arduino’. This is the first part in a 3 part series of posts. Part 1 shows how to generate the simple Infrared carrier frequency on Arduino,
