Yes. CircuitBlocks and the firmware restore both run in your browser at code.circuitmess.com, so there is nothing to install. A Mac, a Chromebook, a Windows PC or a Linux computer all work, as long as you are online and use the right browser.
Which browser to use. Google Chrome, Microsoft Edge, Opera or an up-to-date Firefox, on a desktop or laptop. On a Chromebook, that is the built-in Chrome. On a Mac, avoid Safari: it cannot connect to your device. Phones, iPads and other tablets are not supported.
If your Mac or Chromebook does not see the device
Update. Update your browser, and on a Mac update macOS too: older versions are known to have trouble with the USB connection used for coding.
Use a data cable. Many USB cables only charge. Use the cable from your CircuitMess box, and if your computer only has USB-C ports, a simple USB-C to USB-A adapter lets you use it.
Plug straight in. Avoid hubs, monitors and extension leads, and try a different port.
Keep the device awake. Switch it on and check the screen is lit. Some kits, including Clockstar 2.0, Bit, Codee and Artemis Watch, drop the connection when they go to sleep. On the watches, set Sleep time to OFF in Settings while you code.
Choose it in the pop-up. When you click Connect, the browser asks which device to use. Select yours and confirm.
Drivers. On an older version of macOS, a missing USB-to-serial driver can stop some kits from showing up. Tell us your macOS version and we will point you to the right driver.
There is more detail in My computer doesn't recognise the device when I plug it in. What's wrong? and The firmware restore at code.circuitmess.com fails or cannot find my device.
If it still will not connect, message us here, or email [email protected] with your order number, which kit it is, your exact computer model, operating system version and browser, and what happens when you plug it in. If you can, try another computer and tell us how that went.
