    This project is related to Drones/UAV/UAS. First Part: This project is to modify the existing open source firmware version 4.3.0 for Copter (Multirotor). Project need is to develop boot loader to secure the existing open source firmware. Boot loader should be developed in such a way that it should make the firmware at the microcontroller (autopilot) secure and tamper proof. Boot loader should be bundled /signed with the private key of the our organization and public key should be used to sign/ bundled with the mobile application that is Ground Control App (QGCS in Our case) Note: We are using ardupilot open source firmware and cube orange as autopilot. Second Part: We are using Open source Ground Control Station Android App. The ground control Mobile app QGCS(Q ground control Stat...

    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).

    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...
