We're producing a short series of videos about expanding your HIDIOT. The series will show you how to:
- Get familiar with breadboards
- Understand when to use which type of header, and how to use one
- Connect a display to a HIDIOT via a breadboard
If you've followed our tutorials, you've already made your HIDIOTs blink, which is why we're going to do something a little more interesting by connecting a display.
Normally we just shoot and edit the videos then announce them. We wanted to invite our readers to play along but it can take a while to get parts at reasonable prices. That's why we're announcing the series now.
The first video in the series is a short introduction to breadboards. If you'd like to play along, here's a list of parts to buy, and where to buy them from. We've provided links to Amazon for people who prefer next-day delivery, and Aliexpress for those who'd prefer to pay less and wait for delivery.
- A built and functioning HIDIOT
- Half-sized breadboard (Amazon, Aliexpress)
- 40 pin male 2.54mm single row headers (Amazon, Aliexpress)
- Male-Female Dupont cables (Amazon, Aliexpress)
- 0.96" SSD1306 I2C Oled display (Amazon, Aliexpress)
Amazon total cost: £25.65 (at time of writing)
Aliexpress total cost: £4.65 (at time of writing)
Although Amazon is 5 times the cost of Aliexpress, the turnaround and support may be worth it for some of the above items, particularly if you've never bought this before.
What these links mean
The links provided here are illustrative and do not constitute endorsement of individual products or vendors. In particular, the OLED screens can be very choosy about what they work with and differ from vendor to vendor, even sometimes from order to order. Make sure your OLED screens have 4 pins, (ideally GND VCC SCL SDA when held upright reading from left to right), work with I2C (not SPI) and support 5 volts. Amazon links are affiliate links chosen because of prime delivery support, Aliexpress ones are not.
The first video is a short and gentle intro to breadboards. Over the coming weeks we'll bring out more videos on using headers, jumper cables and connecting a display. We'll also look at the code involved, the protocols used and how to use your own images on your HIDIOT.
If you're new to the HIDIOT, we hope you'll come join us and start adding new things to yours. We designed the HIDIOT so you can make it your own, and this is a big part of that.
And in the meantime if after watching the video you want to go deeper and learn about what's inside a breadboard, the good folks at Science Buddies have a great in-depth article just for you.
