Fintan project 1, Arduino frequency switch

The system will work as follows: 1. Pin 2 will be dedicated to the frequency reading. 2. The reading of the time between each pulse entered will be made through an interruption with the Timer. 3. The frequency limits will be established in global variables for further modification. 4. The information acquired will be displayed through a printout on the serial port of Arduino. 5. A connection diagram will be delivered.

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Easy and fast task. Lets talk.

What is a source of your signal: standart 0/5V logic levels or anything other? Do you need an optoisolation? I work with Arduino since 2010 and have more than 20 years of experience in programming and electronics.

Dear sir I have more than 10 years experience in embedded systems design please check my profile also please message me so that we can discuss

Hello. I have experience with arduino systems. Also i have arduino boards set in my hands for prototyping/testing. I will be happy to help you. Best regards, Nikolay

I'm electrical engineering TA with 10+ years of experience. Experienced in embedded system circuits - Arduino Based - TI MSP430 Based - PIC24FJ - ATmega- etc. experienced with interfacing to GSM/GPRS/WiFi modules - different types of sensors. I can made the desribed sketch and provide you with the fully commented code and make you able to trace the progress through the serial monitor perfectly within few hours.

Dear sir, I can successfully complete this project using 555 timer IC and 74LS14 Schmitt trigger gate or NOT gate. Using these ICs i will design you a frequency counter and compare the output with the given three values (75, 80 and 90Hz) and light three colored LEDs according to the requirement. Please let me know if you are interested. Thank you!

Hello I am an expert in Mechanical/Mechatronics engineering, As I was a double major student. I am certified and with +5 years of experience. Working with professional ethics, including paying attention to all the small details and respecting deadlines are from my principles. my Graduation Project was in field of embedded systems & microcontroller , espicially in ( AUTOSAR Layers & Stacks ) . I am ready to start working on this project as soon as you award it to me. With all these years of experience and professional practices, I am here to ensure your 100% satisfaction without not lateness in time or increase in costs of the project. I also have a hard working team in all fields of engineering , In case you have a multidisciplinary project or your project is big and you want to finish it quickly. ( mechanical constructions ( solidworks & Autocad ) , information security , communication , Apps development , web development ) . please have a look on my portfolio to see some of my done projects. Please contact me if you are interested. Looking forward to hearing from you. Mohamed Salem

i am ready to work on your project . please do message me for details. i have good experience in Arduino programming

Hello, i have already the software and the board , i need just to know the input voltage and the power supply . Regards, Sandu Andrei

I am an experienced BEng. Electrical and Electronics Engineer living in Cyprus. I am specialized in PCB design (EAGLE, Protheus, KiCad), Microcontrollers ESP8266, ESP32, Arduino, RaspberryPi. I have advanced knowledge on C++, Image Processing, Signal Processing, Neural Network, MATLAB and Simulink.

Good day! I am interested in working on your project. Please contact me so that we can discuss the details of your project. Look forward to your answer. Best regards.

I can finish this job in 3 days but i want to know what is the input voltage of your input signal. Then i can start with this project. If your input has minus voltages then i have to design a small circuit for solve that. I am a professional so don't be worry about that. I ll do the job for you.

Hello , I have a many experience with Arduino and I can help you to finish this project. Best Regards
