This work was done to see how small, and secondarily power-efficient, an Arduino/LoRa solution can be, as a preparation for education and measurements in the field. I used a clone (Adafruit Feather 32u4 RFM95), that is software-wise fully compatible with an Arduino and supported by Arduino IDE, including uploading of software, but has slightly more Read more about Evaluating Arduino with LoRa[…]
Don’t forget that the MCU on Netduino and some Arduino boards are powered by 3V3, which means also the inputs and outputs are adapted to 3V3. They generally support up to 5V on digital inputs, but you will get messed up analog values if you make a mistake here, and 3V3 output might not be Read more about Arduino: Don’t forget…[…]
There are several platforms you can use to build prototypes for Arduino-compatible boards. Here are a few good examples, as seen in the picture (left to right): Prototype board for soldering. I buy bare prototype boards that I add 6 and 8 pin stackable headers to. Prototype board with added mini breadboards. Again based on Read more about Arduino: Prototyping[…]
No soldering is required for this Arduino shield, except to build it (it’s sold as a kit), but that was on the other hand quickly done. (notice the semi-pro background sheen, caused by putting the boards on top of a Dell Vostro 3500; tricks of the trade) This shield makes it much easier to wire Read more about Arduino: ProtoScrewShield, the electricians dream[…]
Books I own, and that I have any opinion on. Of these I’ve had the most use of Practical Arduino. Example code is available for all. There are more books coming out weekly now, so it’s clear especially Arduino has become a huge success among hobbyists and professionals. Practical Arduino A good starter book with Read more about Books about Arduino or Netduino[…]
If you intend to buy either/or, this might be of some help. Note that there are many Arduino clones as well as other Arduino-compatible boards running .NET Micro Framework. There are also boards that are not Arduino pin-compatible, but I intentionally stay away from those (both here and in my own use), as they are Read more about Arduino vs Netduino[…]
It’s possible to connect up to 12 small servos (those you find in model air planes etc), to a standard Arduino board, for controlling robots, toys, appliances etc (combining this with the previous IR remote project comes to mind). To be able to power so many servos a separate power supply would be needed. I Read more about Arduino: Servo control[…]
I mentioned in a previous post about Netduino, that a constant risk with playing around with Netduino (and Arduino) is that it becomes a time-waster, as it’s so much fun to work with, and it’s so easy to test ideas, but it’s a great learning tool for MCU programming and new types of sensors and Read more about Arduino: MIDI Remote[…]
This is the smallest Arduino-based design so far. Make your own 1-x1- 22 I-O pin Ardunio Compatible When you think about it (provided you know what Arduino is about) the micro controller takes care of most things in the design, and power supply, USB etc can be taken out. Consequently, there’s not much more than Read more about Arduino goes Mini-Me[…]
LoRa keys the easy way Use this simple tool to generate throwaway LoRa keys, typically for e.g. Arduino projects during education and PoC demos. See Disclaimer below before you use the tool. Disclaimer The Things Network and other services will generate keys for you. Also, off-the-shelf LoRa sensors typically have pre-configured keys. If so, of Read more about Abiro LoRa Keys[…]
