MAKER: ThomasVDD / Translated by: Fun Without End Cherry Soldering tiny SMD components can be quite challenging, but this process can also be automated. It can be completed by applying solder paste and baking it in a (reflow) oven or hot plate (just like a cooking plate in the kitchen). I have seen many DIY … Read more
Guest Post / Dominic Pajak and Sandeep Mistry from the Arduino team Arduino is on a mission to make machine learning easy for everyone. Last year, we announced that TensorFlow Lite Micro is available in the Arduino Library Manager. This allows you to use some ready-made cool ML examples, such as voice recognition, simple machine … Read more
The foundation of the Arduino platform is the AVR instruction set microcontroller, so it is necessary to understand the differences between microcontrollers and Arduino before using Arduino. 1 What is a Microcontroller? A functioning computer consists of several components: Central Processing Unit (CPU) (for computation and control) Random Access Memory (RAM) (for data storage) Read-Only … Read more
