Security Keypad with memory and timestamp

Hello sir, I have experience in designing electronics circuits and can develop hardware compatible smartphone and PC based apps. I also have done a lot of IoT projects and can transform your idea into a fully working product. If you wish we can discuss details in chat. Thanks

Hi, I hope you are doing well. I have worked on similar projects. I have understood your requirements and would like to discuss it further. Looking Forward, Khawaja

Dear, Client. I would like to say this is my fortune to show you my hardware skills. I can bring your idea to live and you can reach the goal absolutely with me. I have 10+ years experience in hardware design (schematic design, PCB design...). My develop tool is Altium Designer, CADENCE. I have designed many high speed devices in embedded system. My recent design is AM5728 Core Board. (quad-core, 1.5GHz, DDR3 4G, EMMC 32G, Gigaethernet, usb3.0,...). And another is PCIe v2.0 to 4x Ethernet (or 4x usb3.1) convertor. All design is passed in several EMC tests. I have designed MEMS tracking board, ultrasonic distance measurement and so on. My design is very stable in industrial environments. I think your design is not difficult. but the most important thing is EMI, EMC. I have been working main hardware developer in large scale industry product company. Designing the PRODUCT is very different from designing the general PCB (test board, kit,...) You can feel everything that is my real skills in hardware development. Look forward to working with you for a long time. Thanks! Hope to see you soon

Hello I am senior microcontroller and Electrical Engineer. I have plenty of experience in firmware development. I have been a lot of Microcontroller developments. I can write the firmware based on PIC and ATMEGA. As I am an Electrical Engineer, I can design the cicuit by the Altium designer. Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I hope we can discuss more details via a private chatting. After you see my profile, you will think I have no experience. I have been developed the complete project, and I have the actual experience. I hope you think again about me I look forward to your response Best regards

I have just read your project and I felt happy to see it. I have experienced for +7 years in this field. Particularly, I have ever done the job like this as you want. I want to hear your advice and discuss in more details. Trust me. If you hire me, i will do my best for you. Thank you.

Hello! To dear client Thanks for sharing your project. I am a firmware and PCB expert. I have wonderful 8+ years experiences in IoT projects using Arduino, ESP8266, BLE, NRF, BT, servo and very familiar with ARM, AVR, PIC. Particularly, I have a lot of experience in various kinds of sensor application. For example, It is that temperature & Humidity Sensor results are sent client's Mobile or Web over WiFi, Bluetooth, Zigbee, W/xbee, etc. I can write PCB, firmware and mobile app for your. I'm sure that you can get more than you expected because of my skill and hard work. Let's discuss more with chatting. Best Regards
