You’ve got 20 bright teenagers, a classful of robots running on Raspberry Pi Zero and an interest in neural networks (NNs). What do you do next? You dig into an Arm machine learning tutorial and use object detection to control the robots’ behaviour…
Getting started with NUCLEO-F411RE and ESP8266
I received my STM32F411RE Nucleo board last weekend (Thanks to Carissa for selecting my idea). Overall board looks good and worth it's price with powerful STM32F411RE and on board ST Link debugger. The only drawback I noticed was missing USB OTG connector…
