Configure a Raspberry without keyboard or screen: the Secret Menu!
For monitoring or remote control applications, where your Raspberry plays the role of a remote station which allows you to acquire a measurement (temperature, image, video) or carry out a remote action (servo, light, sound), it can be useful to simply configure a Raspberry card without using a keyboard or screen. Here is the procedure:…
Tap, Tap, Drop. ADXL345 Accelerometer + Arduino
This content is made available by Adam Meyer, licensed under CC BY-SA 3.0. You know accelerometers right? Yeah… the things that tell your phone how it is orientated. But, believe it or not accelerometers are best suited for something other than sensing orientation. Excuse my oversimplification here, but this is going to help those who don’t…
Raspberry Pi Pico: getting started
Another fun platform is the Raspberry Pi Pico. Its very small size (21*51 mm) and the possibility of programming it in a language close to Python make it a great ally. We will discover how to configure it, how to program it, but also how to open a remote console and have the Pico interpret…
Wooden coat rack
I needed to make a few coat racks or coat hooks to hang behind doors. After a lot of hesitation, I made them using a very simple model. A wooden circle and an inclined strand. Here are the steps. Cutting circles We start by cutting out the circles using the drill press. For this, I…
Burn a bootloader on ATMEGA328P-PU
For those who program on Arduino, sooner or later the desire comes to take the assembly outside of the Arduino card for reasons of consumption, space or cost. Many tips and tutorials exist and after having tried my hand at it, one more will not be too much, especially if you too have not really…
Programs selection for TI-92 + and Voyage 200
I have recently acquired a TI-92+ and a Voyage 200 from Texas Instrument, and I immediately decided to gather resources and programs for these calculators. Unfortunately, these models are quite old and the websites that list such resources are gradually closing. Here is a collection of programs gathered on a dedicated page for the nostalgic….
Muxing Around With The CD74HC4067 + Arduino
This content is made available by Adam Meyer, licensed under CC BY-SA 3.0. Have you ever found yourself running out of pins to read an array of analog sensors? Don’t worry, you’re not alone, it happens to the best of us, and there is something you can do about it. An analog / digital multiplexer…
Electronic initiation #1 – LED and push button
In this tutorial, we will learn how to use a prototyping plate to make a simple LED and push button assembly. To make this setup you will need: Mounting The assembly is carried out using the diagram and the video below: Functioning To understand this assembly, we start from the red wire of the battery. The wire…
Arduino: prepare spare part for your Uno Board (ATMEGA328P)
I experienced some regular uploading issues, and I am not th elonly one reading the forum (http://forum.arduino.cc/index.php?topic=574627.0) . Then I decided to prepare some spare parts. Here, I prepare chips for my Arduino Uno R3 board. Explanations The heart of Arduino board is the removable chip. IT is called ATMEGA328P. THis chip can be bought…
Weather station powered with Arduino
Thanks to all the sensors compatible with Arduino board, it is very easy to build a complete weather station. Here is how I proceed. About components To achieve this weather station, one should first choose what has to be monitored. I chose temperature, humidity and atmospheric pressure. One could also consider the amount of rain,…
