Hello,

I'm having problems when trying to connect cables to this module(also one sd card module with the same pins).

I am 99% sure that is has to do with the cables,

at first i just used single dupont cables and now i switched to 4x1 and 6x1 connectors.

What happens is that the microcontroller loses connection to the modules, but only sometimes. When i shake the box a bit or plug and unplug the microcontroller it works again(not always, it's very inconsistent).

I tried removing the pins and soldering the cables directly onto the board, but that didn't work and i just broke a module trying to remove the pins.

Thank you very much for any help

Integration with gamemaker

I'm developing hands-on STEAM/maker workshops for children where they design and build interactive creations using an Arduino Nano, servos, ultrasonic sensors, arcade buttons and WS2812B LED strips.

The idea is for children to connect the components themselves (with adult guidance), so I need something simple, reliable, safe and independently powered so they can take their creations home.

I paid a PCB designer to develop a custom Nano carrier board with JST-XH connectors, an ON/OFF switch and external power input.

I'm currently facing two problems:

1. Power: The board works when I connect a USB power bank directly to the Nano, but powering through the PCB's external JST-PH input hasn't worked reliably using a 4×AA battery holder. I've also tried a USB-C power bank connection, with intermittent results. The power LED sometimes flickers when I touch the board's switch.
2. Wiring: I'm currently using JST-XH-to-female-Dupont cables, followed by male-to-male jumper wires to connect components such as servos. It's messy and not ideal for children assembling their own projects.

I'm wondering whether I should try to salvage the custom PCBs or return to a standard Nano expansion shield, which has worked reliably in my tests.

What would you recommend for simplifying the connections and providing safe, reliable battery power? Is powering the Nano directly via USB suitable when running a servo, ultrasonic sensor and LEDs together, or should I be using a different power arrangement?

I'd really appreciate advice from anyone who's built similar educational electronics kits!

Have a good time, everyone! I'd like to get some advice, I know it's stupid, but I need some advice. Do you think it is possible to combine this board with an Arduino rgb sensor? I'm just curious, but I'm afraid I'll burn it. I started doing robotics relatively recently. And your advice will be very useful and important to me.

Based on patmcbennets code. Expanded to 8 steps via 4051.Added tempo control via knob. Added 3 vc out plugs and vc in Sounds really good for arduino :)

We just trained a new policy and we're really looking forward to the Arduino community building and sharing more motions!

I just got the nrf24l01, the antenna version, and I took a glance and noticed so many dots. I'm assuming they are all vias but is having so many of them normal or is it some sort of defect. I have the normal nrf24s without the antenna connector and they don't have so many vias.

As a big lover of various dot matrix displays I couldn't find a good set of tiny fonts, so I made my own. They are hand drawn with some help of AI with generating different variants and AdafruitGFX header files. They have extended latin support, so diacritics and special characters also work!

Github is set up, so let me know how you like them!
