I'm a newbie, but working on controlling some leftover smd5050 LED light strip that I didn't want to waste.
I replicated a project that uses an ESP32 to control an old Meade ETX telescope with the SkyWatcher Synscan Pro app on a phone....like a year ago...barely got it working to the point of moving the scope with the app and lost my good sky viewing spot access.
I really need to get an old HP rack mounted lab power supply working at some point soon. It only has a HPIB interface and I want to control it with an arduino but am still too intimidated to try.
Currently setting up for a keyboard project, though IDK if I'm going with Arduino, ESP32, Nordic Wireless (leaning towards this), RP2040 or something I haven't thought for the MCUs.
If there's anyone well versed in working with the Nordic SDK I'd love to pick their brain though. Hoping to use the Nordic Dongle for a couple of small projects like a Zigbee gateway for Home Assistant and using the nordic wireless protocol to act as a master with two nordic chips as the slave sides for the keyboard project.
Nordic looks interesting, and is now on the list for as/when I need zigbee. - No experience of it sorry. The PI unit is attractive for it's operating voltage... I'm currently struggling with getting an esp32 powered nicely from a lithium battery. Have to say though that I'm really impressed with the esp32.
I might be a little late to this thread. I'm currently working on two robots, the first one is a hexapod that I'm rebuilding and reprogramming, using a teensy 4.0, while not technically an arduino it uses the arduino ide so I'll count it. The second one is a smaller autonomous rover with a lidar, it uses a raspberry pi 4b as the brains and has an arduino nano to move the motors and take movement commands. It runs on ros, and I can now click on a map in rviz to have it move there. Currently working on pathing. The plan is to move the lidar to the hexapod once I'm done with the rover and the hexapod.
Sounds an excellent project. Will you put it on GitHub or publish elsewhere? What battery life are you looking at with a 4b and all the mechatronics?
I'm currently creating my own smart clock with some sensors and a web interface, I'm hoping to learn a lot about machining and networking/database management and I'm currently learning a lot about basic bitcrusher communication protocols. It's been a blast!
So.. various things:
-an LED clock -dsp learning with a Nicla Vision (i want to learn how to implement digital filters and use them on the signal sampled from the on-board mic) -a custom keypad for special characters -a tool to use at work to check encoders signals
