ESP32s are surprisingly good AI lie detectors.

Arduino has transformed the way students, hobbyists, and engineers learn embedded systems and automation. From sensing objects and controlling motors to displaying information, Arduino provides a ...

AM232X is a sensor similar to the DHT12 with an I2C interface. Although in theory this could enable multiple sensors on one bus the AM232X has a fixed address 0x5C so one need to implement a ...

If you're searching for the best oscilloscope, you've come to the right place. We personally tested a variety of models—from beginner-friendly units to advanced scopes built for professional ...

Excel user interface to configure the LEDs without programming at all improved by the engagement of Pattern Configurator and Program Generator! To start the excel program press the Win+r key together ...

Quantum computing promises to revolutionize computing and unlock solutions to many intractable problems. But realizing this vast potential rests on building reliable quantum bits, or qubits, that can ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Power MOSFETs are ideal for controlling large loads from an Arduino or Raspberry Pi. Placing the MOSFET in the high side is often preferable but demands very high gate voltages — much higher than a ...

Building an Arduino oscilloscope with OLED display is an affordable way for electronics hobbyists and students to visualize electrical waveforms without spending hundreds of dollars on commercial ...

Two-photon microscopy has enabled high-resolution imaging of neuroactivity at depth within scattering brain tissue. However, its various realizations have not overcome the tradeoffs between speed and ...

In the study of ballistics, you can do very little without knowing the velocity of a projectile. Whether you need to hit a target at over a mile, check if a paintball gun is safe for opposing players, ...

Synchronization 1 —perhaps the most widely studied phenomenon in network dynamics 2,3,4 —has been observed in many contexts, including both natural systems (for example, circadian clock cells 5,6,7, ...
