Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

In last week's installment, we showed how to get started with Csound. This week we take it to the next step by constructing a homemade MIDI controller circuit and use the new device to control Csound ...

Renesas Electronics Europe achieved VDE (the German Association for Electrical, Electronic & Information Technologies) certification for its IEC60335-compliant self-test software aimed at its RX100 ...

Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one ...

A microprocessor is an integrated circuit that contains no memory. A microcontroller has the ability to store information. The size of a circuit can be significantly reduced. This is because ...

Battery-charger-control designers face a fundamental choice: to use a part from the rich selection of dedicated charge-control ICs available from many vendors or to use a programmable microcontroller.
