    Only a hardware development is required. No code. Time for project development: max 6 days. Sensor used for input: piezoelectric Microcontroller used to receive the amplified sound: ESP32. Output voltage range: 0-3.3V. Midpoint Bias near V=1.65V (half of 3.3V) Operational Amplifier model will be defined before start the project. We have some circuits tested but with problems as clipping and sensitivity signal. Signal amplification should be the higer possible. In oder to avoid the noise, a 10-15Hz filter can be used. We can cut any input or output signal above a specific voltage threshold Battery used: 1x3.7V (voltage used as input for sensor = 3.3V) Software to use: KiCad for schematic and any other software for simulate it (for example LTspice). Project files will be pr...

    I’m looking forward to design a robust AC input filter for HiLink AC DC converter in which an AVR project is running. And I would like to add some prime features like inrush current protection, AC line transients / spike protection as well as inductive load back EMF protection which may sometimes reset the microcontroller. Please note we have only phase and neutral, so earth connection for the filter circuit. Please find the attached file of the proposed project.

    Microcontroller is considered as the backbone of Embedded System& it's most important feature is: "It can think". A Microcontroller looks like a simple electronics chip, but in actual its too powerful (also called Embedded Computer) because its programmable. Using programming code, we can control all I/O pins of a micontroller and can perform multiple functions. Before microcontrollers, DLD gates were used to create logics i.e. adding delays, turning signals ON/OFF etc. DLD is still in practice for small projects but if you are working on big industrial projects, then DLD circuits become too messy & thus too difficult to handle. In below figure, I have added two circuits of traffic signal lights: Left Circuit: 555 Timer is used for creating the LED sequ...

    I am looking for a freelancer to help me create an app that will control a Freenove microcontroller with on-board camera, a stepper motor, and read out temperature values from an IR thermometer. I have most of the physical components and can connect them up, but I was hoping for some help with the UI. As we'll be working with physical components, it's important to be located in Brisbane, Australia or have access to the components (we can work this into the price). Freenove kits are readily available on Amazon for under $50 AUD. We have a fairly tight timeline, so please let us know if you're interested.

    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...

These detectors will be able to spot elephants before they reach a farm or village and warn rangers in that area who can deal with that situation. This will prevent human-elephant-conflict.

If successful then the microcontroller turns the relay on and in turn the machine can start. Details: I need the Wemos D1 Mini programmed to handle primarily 3 tasks, namely: 1. Receive a keyboard input and send that along to a website using web parameters (Website already built) 2. Read the website for a response (read param1) 3. If the response is good, turn the relay on which in turn enables the machine to start (Relay is directly connected to the Wemos d1 mini)
