Figure 4 shows the microcontroller section of the board which mainly consists of the STM32G030F6 ... .. OLED display module. Figure 4. The microcontroller section of the circuit. PCB layout Figure 5. PCB layout of the AC energy meter circuit. Figure 5 shows the PCB layout of the design. It’s a two-layer PCB board with a mixture of SMD ...
.. interface ICs that integrates the analog signal prosessing circuit. I built a pocket sized thermocouple temperature meter with it. Foto 1. Thermocouple Temperature Meter Principles Seebeck effect When apply a temperature gradient to ...
.. with LED level bar graph that you find on most stereo systems or amplifiers. This is your chance to build your own LED VU meter that you can link to your amp and watch it in action. The application is based on LM3915 chip. This is a ...
Easy homemade anemometer, this goes together quickly if you have the parts laying around. This is basically a mini wind generator; the spinning motor produces a current that a multimeter reads. Ingredients: 1 cheap $3 analog multimeter 3 or 4 ...
.. I managed to persuade myself to make a really powerful capacitance meter. This is an autoranged version, which means one does not need to adjust the range settings. Furthermore, the ...
.. main application of the accelerometer is either for sensing tilt or sensing acceleration. For this application A G-Force meter for my car will be made to see how many G's I pull while driving. Below is an example of what the Personal ...
.. would be able to log on to a SNTP time server, get the correct time, and display the HOURS digit on one analog panel meter, the MINUTES digit on the next, and the SECONDS digit on the last. What a cool way to display the correct time! ...
