I am an EE engineer. I have lots of experience designing circuitry in both digital and analog circuits and in programming field worked with Xilinx and Altera FPGA boards writing VHDL and embedded C for NIOS II (field of interest). I have a background in digital design. I also worked with microcontrollers such as MSP430, Arduino, PIC, etc with both Assembly and C language. ABOUT YOUR PROJECT, It could be done using analog electronics with an adjustable range for these carts(if this is an alarm) or using MCU to have feedback about range or other possible things to show. I have done lots of similar projects before and can handle your project easily. We can discuss it more over chat. Regards,

Hello, I have 6 years of experience of working on product development, circuit designing, PCB layout and firmware programming. I have worked end-to-end on various products with varied levels of complexities, which included features like motor control, MCU programming, BLE, interfacing of different sensors using USART, SPI, I2C etc. Although I have decent enough experience of working with corporate as well as academia, I am new to freelancing. Therefore, I am looking for good learning opportunity and networking. I believe that, I would be able to deliver the work effectively. You can go through my profile for further details. Looking forward for your positive reply.
