Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...
Several years ago [Michael Davis] built a charge controller for his wind turbine and published his construction plans online. This build became quite popular, especially among people that live in ...
The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...
LEDs find their way into applications that range from high-end video displays to low-end lighting applications. Designers often need only some of the functions of a dedicated LED driver but can’t ...
The 555 timer IC has been reinvented—again. Signetics introduced the enormously popular chip back in 1971, and it quickly became a big hit. Myriad application circuits have used it throughout the ...
