Alex Eames did a Kickstarter a while ago for the RasPiO Duino, which is a GPIO add-on board for the Raspberry Pi that gives you an ATMega 328P-PU chip (which is the same as an Arduino Uno) as well as loads of broken-out pins and a small prototyping area.
He has now launched a new kit to accompany the Duino board. In the kit you get:
- a 20×4 LCD with blue backlight and pre-soldered i2c backpack, pre-calibrated and fully tested
- 2 x TMP-36 analog temperature sensors
- 1 two-way female header
- 1 four-way female header
- 20 x 10cm M-F jumper wires
He has written a guide to go along with the kit (which is well-written and comprehensive as usual) as well as a sample sketch for the Duino that can be uploaded to the board to get it to read the temperature sensors and display the output on the screen.
I’ve used one of these types of screens before with the Picorder and 20×4 characters is a lot of space to work with.
It’s a tidy package that costs £20 plus shipping (£2). You can also get a Duino bundled in and that bundle will cost you £30 plus shipping.
