I am a student of Software Engineering and I've been practically working in these fields since 9 years. I'll help you on your Arduino and NodeMcu projects. I'll guide you about Arduino and help you in coding from basics to higher level I can also help you if you are stuck somewhere in your project or if you need any assistance. I can help you out in dealing with many modules like bluetooth, sonar, RFID, thermal printer, level shifting, gsm, ethernet, etc Please, tell me details of your project before you place an order. The price depends upon complexity of your project. I'll try my best to solve your problems. Thank you.
