This PCB was planed for Sainsmart 4-Channel 5V Relay Module. It is alss possible to measure the current if ACS712 is connected to the prepared header. ACS Generic male header - 3 pins pin spacing ...

Abstract: Lithium-ion (Li-ion) batteries are commonly used in electric vehicle (EV) applications due to their higher energy density, longer lifespan, and better performance. However, there are few ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

We are all familiar enough by now with the succession of boards that have come from Raspberry Pi in Cambridge over the years, and when a new one comes out we’ve got a pretty good idea what to expect.
