Figure 1 555 VCO discharges timing cap C1 completely to the negative rail via a Reset pulse. The nay-sayers’ case hinged on a perceived inability of the 555 architecture to completely discharge the ...

Calculate the frequency and/or duty cycle of an astable 555 timer.

In the early 2000s, the idea that you could write programs on microcontrollers that did things in the physical world, like run motors or light up LEDs, was kind of new. At the time, most people ...

The negative terminal (cathode) of each LED is then connected to the ground (GND) of the ESP32. This establishes a complete electrical circuit for each LED. When a GPIO pin is set to HIGH, it sends a ...

Users can easily configure button mappings, customise LED patterns, and fine-tune motion sensing features. It can function as a remote control, a Bluetooth gamepad, or even a smart automation ...

Powered from a 24 V supply it can drive up to six white LEDs connected in series. The LT3092 datasheet indicates that the IC can dissipate a maximum of about 1 W of power. It also shows a basic ...

Bourns, Inc. announced its new Model ZV50S2220452NIR1 High Surge Multilayer Varistor. Offered in a compact 2220 surface mount package, these ruggedized multilayer varistors are specifically designed ...

The first thing you need to do is assemble your circuit. I talk quite a bit about how circuits work and the details about LEDs on the Circuit Bugs activity. If you need more details, hop over there.

Putting candles near your windows is a great way to welcome a dark night. It’s pretty dangerous to use real candles, so you should choose the brightest battery operated window candles that won’t ...
