This test circuit for electromechanical relays uses a microcontroller to control the relay under test through an optocoupler. A power supply and load produce current in the relay contacts.

Like any measurement system, though, 4–20-mA loops need calibrating. There are many loop calibrators on the market (Figure 2 ), but they can cost up to $2000. As an alternative, we’ve designed and ...

Verifying that automotive microcontroller test programs do not exhibit voltage excursions is a requirement to ensure quality. It can be a very time-consuming task.

This simple circuit based on a PIC microcontroller generates a Gaussian analog output. However, unlike most circuits, it does not need a DAC to transform the digital bits into an analog signal ...

Such circuits could lead to a biochemical microcontroller, of sorts, for biological cells and other complex chemical systems.

You can do this by adding a button to your microcontroller circuit or using some creative methods and subroutines in your microcontroller or Csound code.

Circuit Check, a global leader in turnkey functional test systems across medical, automotive, industrial, military/aerospace, and emerging AI applications, today announced the acquisition of ...

The Raspberry Pi Foundation has announced the Raspberry Pi Pico, a $4 microcontroller. The computer features the new RP2040, which will also show up in other products, thanks to the foundation’s ...
