Hi Bill, the Uno is rather the same as the nano, both have the same MCU. The Uno's PCB is only as big as the nano IO Shield.

There could be a 'nano 33 xx' -- but - it's aa... (More)

If you take a look into the Ottoxxx Library code:

Otto.home moves all the servos to '90' and then detaches all servos and sets Otto.resting = true..

Try to move the first 'Otto.Home()' from loop() to setup() and the two... (More)

Hi @Jan van Heck13, with the actual library and sketch I don't see an easy solution. In the sketch the library functions are called one after the other and the functions are all "blocking". A pin change interrupt is... (More)

You followed the wrong video and bricked your servo now..

The servo modification should be done like shown in this video

To use your modified servos you'll need a (new) motor driver now (L298N).

see this video too

For use... (More)

I have never measured the current at an IO pin - it's calculating only. I'd suggest to connect the unknown "circuit" to a 5Volt DC Supply first and do the mA measure that way before driving it with an IO... (More)

When understanding correctly: You can't choose another matrix display inside a moving function. That's correct, because matrix display and moving are different functions in the library. Try to move only one step, then set a new matrix display, do some... (More)

The code is a whole sketch. Open a new file, mark all the existing lines in the new file (setup() & loop()). Then copy this code and paste it into the new sketch.

But to compile it, you have to... (More)

In the comments at the "getting the noise sensor to work" post Camilo posted the documentation for the noise sensor. It has a digital output that is normally high and will drop to low if a noise is detected.

Batteries are too weak? Did you connect batteries or accumulators to the Vin pins? Servos need to much power to move? Try to connect the VCC and GND wires from the bluetooth modul to the V and G Pins by... (More)
