Simple Power Inverter Circuit. Using PIC12F508A 12V TO 230V This project is very simple for every one to make. It's very beautiful with it's minimal component design with out compromising any degradation in performance.The heart of this project is a low cost Microcontroller available in the market.which is configured as a 50 hz square wave oscillator. You can Download the Firmware and Designs from here.     Download Steps to Follow  Download the design files and extract with  winrar.  It will ask for a password just enter MADEB36970  After the extraction you get HEX file of firmware and pdf files of PCB Layot's and Circuit Diagram. Print the bottom PCB Layout in actual size A4 using Laser printer on a photo glossy paper. Then Make the PCB  and Assemble the components as per the Circuit diagram and PCB Top Layout's. If you are a beginner in making PCB at home   Watch This or This video.   After finis...

This Robot will follow a black line that is 1.5cm to 3cm wide. Here we do not use any Microcontroller and Motor driver IC's. so this project is pretty simple. You can Download the Designs from here. Download Steps to follow  Download the design files and extract with winrar.   After the extraction you get 3 PDF files PCB Layout and Circuit Diagram. Print the bottom PCB Layout in actual size A4 using Laser printer on a photo glossy paper. Then Make the PCB  and Assemble the components as per the Circuit diagram and PCB Top Layout. Solder it well and wire the Circuit board to both Motors  Adjust the sensor sensitivity by adjusting the 10k presets on the PCB. left preset for the Left sensor and Motor and Right preset for the Right sensor and Motor. You can use black and white surfaces to adjust the sensitivity to the threshold point. The threshold point is the Motor barely start's rotation when the sensor on white surface and suddenly sto...
