In some rare cases, it is found that old MPLab or old PICKIT2 firmware versions work better than the newer ones. If this is the case, Microchip has a page dedicated to their old software and firmware that you will find interesting.

SCR.png dv/dt Triggering of a SCR will be performed as below. - When the device is forward biased, J1 and J3 are forward biased, J2 is reverse biased. - Junction J2 behaves as a capacitor, due to the charges existing across the junction. - If voltage across the device is V, the charge by Q and capa...

We need to first connect the ACS712 current sensor properly to an analogue input pin. The value read from the sensor is proportional to current measured on the sensing terminals.

Hello It is really good to hear that you have stepped in to practical micros. However, I haven't use this circuit to program the ATMegas, so can't give you much help on this. However the chip ID is coming from the chip itself. No bootloader is necessary for that, a blank chip should do it. I recomme...

I respect your thought on Sri Lankan products. But UK version of the Raspberry Pi is Made in the UK and fantastic in quality. So as a help to the effort on building such a wonderful device, TRONIC.LK respects and supports Raspberry Pi original product. We do the same respect to Original Arduino prod...

Features: 1. Can detect the flame, or wavelength of the light source in the range of 760 nm to 1100 nm, and the the lighter test flame distance is 80cm, the greater the flame, the test distance farther 2. Detection angle of about 60 degrees, the flame spectrum is particularly sensitive 3. The compar...
