The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

Here is the circuit of a compact yet inexpensive automatic anchor light integrated with an ambient light sensor that turns it on and off automatically.

When light strikes the photodiode’s active region, current flows from cathode to anode. Ideally, this entire photocurrent ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

Learn how to build a WiFi-controlled drone using ESP32 modules and MPU6050 IMU. This DIY project offers stability control, smartphone control, and easy upgradability. Get step-by-step instructions and ...

Given the performance decay of high-power light-emitting diode (LED) chips over time and package condition changes, having a reliable output light for sensitive applications is a point of concern. In ...

In the first part of this audio synthesis series, we explored the block diagram and key functions of the Basic Synth software. In this concluding installment about the MiniPhonic, we turn our ...
