Digital electronics and Analog electronics doesn’t mix easily. A Microcontroller can’t get analog values unless an Analog-to-Digital converter is used, however, you may find a little complicated the use of an ADC and it need lots of Input/Output ports. Some Microcontrollers, like the small 8-pin Microchip PIC 12F675, do have an ADC integrated, but […]

Step 1: Gather the Materials! So with any prototyping project this really shouldn’t be the first step… But we’re gonna go ahead and do it cuz it’s just so darn fun! Just a little disclosure, we’ll be using the ACT4088 picked because it’s cheap and has an adjustable VOut along with a max of 1.5A

There’re many, who built the Easy Programmer or C-52 EvaluationBoard, asking for the RS232C level converter chip, DS275. Many have changedto MAX232 instead, because of not available in his home. Here is anothersimple and cheap circuit using small signal transistor providing TTL toRS232C level converter. A circuit diagram shown above was used two small signal

As a maker, we are always looking for the best way to power our projects. Usually, buck and boost converters are a considerable part of our project, because without good power, then everything else can be compromised. As important as it is, one does not want to splurge huge amounts of money on something that

STMicroelectronics STEVAL-LLL009V1 Digitally Controlled 300W Power Supply consists of power factor correction (PFC) and half-bridge LCC resonant converter power stages. An STM32F334R8 microcontroller implements DC-DC and output synchronous rectification digital control, while the PFC is driven in transition mode by the L6562AT controller. To ensure maximum efficiency, MDmesh K5 and MDmesh DK5 Power MOSFETs are used in

Note : This hack is only needed if your usb-serial does not support the BREAK functionality. Else, it may work with as it is, with the usual programming software like PicPgm, WinPic etc. Usually the DIY programmers like JDM do not work for usb-serial converters. Voltage levels, timings, and missing functionality like setbreak() causes issues.
