Re: SSD1306 128x64 Pixel uOLED display module (HCMODU0050&2)

You need to move resistor R3 to pads R1 and resistor R5 to pads R8. Connections will then be as follows: OLED Module.......Uno GND...................GND VCC..................+5V D0.....................A5 (SCK) D1.....................A4 (SDA/Din) RESET.................D8 (if using HCOLED library) DC ...

Re: IR Remote Control Kit (HCKITS0006)

Thanks for the information and glad you managed to fix the sketch. As you're no longer waiting on a fix I'll get the example in the first post updated as soon as convenient then.

Re: IR Remote Control Kit (HCKITS0006)

Sorry about that, and thanks for pointing it out. I wasn’t aware that the manufacture had changed the layout. Yours sounds like it’s very similar to the one in the image but I guess the keys have different key codes assigned to them. As it’s boxing day I won’t be able to check the stock until tomorr...

Re: Hobby Components 8x8x8 Cube Kit (HCKITS0050)

Glad you enjoyed building it. If you're using the USB to serial cable that came with the kit it's likely that you will need to install a driver for it. You can find OSX drivers on the Prolific website here:

Re: Dupont crimping tool

We don't at the moment I'm afraid. I don't know if this will help but If you've not got many to do I just use a small pair of needle-nose pliers. I use the end of the pliers to fold over each tab one at a time and then put them in between the pliers to crimp them.

Re: HCDisplay Arduino library for Hobby Components Displays

This would unfortunately be quite a tricky task as the internal I/O hardware of an Arm device differs quite significantly to an Atmel based ATMega microcontroller. To modify the library you'll need to be familiar in how to configure the ports of the Arm devices at a hardware level. If you have some ...

Re: W1209 Temperature control Switch (HCTHER0006)

I've have been asked this question in the past so maybe there is either some misinformation or a there is a variant/older version of this product that doesn't store settings. Obviously I cant comment on versions sold elsewhere but the ones we sell do keep their settings when power is removed.

Re: W1209 Temperature control Switch (HCTHER0006)

Yes settings are saved in EEPROM and so will be retained if power is removed from the module

Re: HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules

I've just checked but I'm not able to replicate the error. Can you provide me the following information: What operating system are you using ? What version of Arduino IDE ? What Arduino board are you compiling the sketch for ? Can you also cut and paste the full output from the bottom of the Arduino...

Re: Altera FPGA/CPLD USB programmer (HCDVBD0007)

These steps assume you are using a USB blaster programmer snd it is connected to your CPLD/FPGA development board: 1) In the Quartus main screen open up the programmer window by clicking on the 'Tools' menu and selecting 'programmer'. 2) In the programmer window that just opened up select your progr...
