Various robot can be used in different applications, alarm projects or a simple useful circuit also has proteus schema and ares pressure circuit. Pictures of the circuit Source: nabilkarami.com/projects.php?show=project&id=3 alternative link:…
Relay control circuit is built on a computer via the rs232 port com pic16f628 microcontroller RF modules (433 mhz) can be controlled wirelessly with 8 relay with rs232 communication max232 project belongs to isis simulation and ares pcb drawings source picbasic codes. One of the buttons while the other two have the control program with…
Circuit ne555 and 74393 circuits based on single piece is tested with the rgb led Strip Ribbon if you want to use more than the output of the led with the necessary tubing circuit transistors used in 12v 74393 works with the integration of LEDs with 100 k potentiometer connected to 555 speed can be…
aha before the “AVR Test Kit (professional usb ISP programmer)” shared the most detailed I’ve ever tested, the project experiment kits, a more advanced system, similar to the project development was one of the cards made for ATmega32. I2C, USB, display, led, microphone input, output units, stepper motor driver, etc.. a lot of vehicles on…
I have seen a site similar to the classic, but darlington transistor-quality hifi amplifier circuit. very few elements with the less clean up audio element that account. the beautiful thing about all the details, there is a list of the schema, pcb, set of illustrated information on the flow of material, calm, etc.. 100W amplifier…
13.8V 40 Amp “switch mode power supply” SMPS circuit ATX power supply structure was inspired by a more powerful version could be called the primary solid in the driver transistors, BJTs instead of MOSFETs used driver transformer the etd29 secondary section TL494 is controlled by a circuit over current, over temperature protection have a current…
BJT and MOSFET transistors based on active antenna circuit’s two pieces instead of the normal antenna amplifier circuit and PCB antenna through the first circuit made of high quality at a radio antenna, and 2N3866 MOSFET transistors have 2sj310. In 17.2khz active antenna circuit 2N3866 transistor used in crystalline and 4MHz. Circuit diagrams and printed…
IO board with PIC18F4550 microcontroller based on the pic accomplished many projects and have visual basic source code open source project müasit to their development PIC18F4550 analog input and digital input and output ports via USB port control a lot of reading done .. Examples; USB Relay Controller (open, close) USB LCD control USB Volt,…
