Re: 433MHz Wireless Modules MX-FS-03V & MX-05 (HCMODU0007)

Is it possible to communicate with an IP address with this combo? I'd like to send sensor data from outside (Arduino nano) via WLAN to a RasPi or PC to log that data. These modules are not compatible with wifi so you can't use one to directly connect to a Wifi router. Until now I only found Arduino...

Re: HCPCA9685 - Library for PCA9685 16ch 12bit PWM controller

You can do something similar with the HCPCA9685. What you're actually doing is making two copies (instances) of the library, giving each instance a different name, and then assigning one to the I2C address of the first module and the other to the I2C address of the second module. Here is an example ...

Yeah that looks like a mistake. I'll get that corrected - thanks.

Re: HCMotor Arduino library for driving DC and stepper motors.

It's good that you are taking a look at the datasheet but for a beginner hardware timers are a relatively advanced feature and so can seem very daunting. Understanding how they work involves understanding several advance concepts that are normally hidden away from you when writing normal Arduino ske...

Re: HCMotor Arduino library for driving DC and stepper motors.

The 32U4 does have hardware timers but the code to set them up and use them is different to the timers in the ATMega328 which is why the library doesn't work when you try to compile it for the 32U4.

Re: HCMotor Arduino library for driving DC and stepper motors.

The library uses a hardware timer that is specific to the ATMega328 which is the device used in Arduino Unos, Nanos, pro minis, etc. Unfortunately it is not compatible with 32U4 based boards which is why you're seeing those errors.

Re: CH340 USB to TTL Serial Adaptor (HCMODU0076)

Sorry to hear that you are having issues. I would like to confirm however that although the supply output is switchable between 3.3 and 5V the TTL outputs are 5V TTL only. Here is a quote from our product page (and first post of this thread): The module includes a small switch which allows the volta...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

It looks great. I did wonder why you wanted to make it dimmer but now I see. I've given your YouTube videos a thumbs up and added the link to your project to the first post of this thread.
