I have successfully built a 555 timer circuit that with a 12-15VDC input switches between 0v and 740mV on the output every 3.3 seconds. I need to build an oscillator circuit using 555 timer IC, capacitors, resistors, and 12v, 3.3v, and 1.7v LEDs (those are the only components I will have available for some time). The oscillator circuit needs to cycle between approximately 250mV and 750mV approximately every 3-3.5 seconds.

...What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid. I'd prefer it if you have the display at your end and can test the firmware on Arduino and test the HMI interface on the display parallely. Looking forward to hear from you. If possible, please share your past work sa...

We have an RFID Card + QR code reader, developed with NXP PN7150 IC, a QR Code reader module, ESP32 as the microcontroller, and some other peripherals. The PCB ,antenna tuning, code(micropython)is done in-house. The RFID card reader is used to read , ISO14443A ( MIFARE, Desfire, ) and ISO15693 Cards. Only CSN reading is done for now and no key or key management is implemented whatsoever. We are successfully reading the above cards. Now, we are facing a few problems in the functionality 1- The read distance is very low (only about 15 mm read distance for mifare, desfire and 45 mm for iso15693 cards, this should ideally be around 45 and 60 mm respectively.) 2- The read speed is a little bit less than optimal, the card has to be presented and held for a little less than 1 second, t...

...spinning. This is not a good design as each time it hits the switch it 'slows' it down from spinning. So we want to redesign this system as basic as possible using a 3D HALL SENSOR. So it detects the spinning, which way it is spinning, then triggers opto isolator output depending on which way it is spinning, clock wise or anti clock wise. New circuit board will - Detect spinning - Detect clock wise or anticlockwise - Send output depending on direction to an opt isolator. Board Design should include. 12v Input(marked +, -) 3 pin output (opto isolated), (white violet, white blue and green black(has diode). Output 'circuit' should have status leds to show which is actually being triggered and it's working. (eg white violet, or white blue) May ...
