Story Wiscore: Integrating Arduino with Alexa As part of the series of tutorials for the Wiscore Alexa AVS EVK, we will see how to integrate Arduino boards (Uno, Leonardo, Due etc) directly with Alexa Voice Service. The Wiscore board provides the means to communicate with other devices via the UARTs. We will in depth on how to enable one of the UARTs, connect an Arduino to the EVK and then communicate over ...

It’s been a while since I posted a new article, a delay at least partly due to me herniating a disc in my neck which left me completely unable to look downwards for any length of time and as you’ll know all too well you can’t work on circuit boards without peering down at them. Look after your neck and back folks, and I mean that seriously. Well I’m back now and I’ve got a lot of ideas for articles spinning ...

The ESP8266 is a great tool for enabling your project to access the internet. You can plug it into an Arduino easily as shown and allow your project to communicate through the internet. Or even more exciting, to control it from anywhere in the world! The ESP8266 is a very low-cost module that comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device an ...

Quickly testing a GPIO pin To set pin GPIO_PH1 as an output: sudo su (Enter your user password. Defaults to "ubuntu") # See which pins are currently configured as GPIO, and what their state is. cat /sys/kernel/debug/gpio # Validate that the entry for the Tegra GPIO controller has a base value of 0. If not, add on whatever the base value is to the “57” in the commands below. echo 57 > /sys/class/gpio/expo ...
