I’m working with a Keyestudio KS4070 4-wheel Bluetooth car that my daughter assembled, but the current sketch isn’t doing what it should. With its line-tracking module, ultrasonic range sensor, and infrared receiver all wired in and verified, the car still refuses to: • stay on the black line, • swerve around any obstacle in its path, and • pause precisely at programmed checkpoints. I need a clean, well-commented Arduino sketch delivered today that makes those three behaviours rock-solid. Please structure the code into clear functions for line detection, obstacle avoidance, and stop-point handling so future tweaks are easy. Serial-print debug messages are welcome but keep them toggle-able with a macro or flag. Acceptance criteria • Upload sketch, ...

I already have a working PIC-based board, but the current firmware was written for a different ranging device. I now need the code modified so the board reads an HC-SR04 ultrasonic module through a single digital I/O line (trigger and echo are already wired to that pin via a resistor network). Once the distance reading is in place, the control logic must raise an “obstacle” flag whenever the measured range drops below 1.4 m; anything beyond that is considered clear. I will give access to my system where you can modify code and also I have test hardware which i can do testing with, I currently compile in MPLAB X with XC8, the schematic showing the SR04 connection, and a short description of how the obstacle flag is used elsewhere in the program.

I’m ready to move one of our production processes onto a fully automated platform and need an experienced PLC specialist to make it happen. This is an industrial environment, so reliability, clear documentation, and compliance with plant standards are non-negotiable. You’ll start by reviewing the existing manual workflow with me, then design a PLC-based control strategy that keeps safety interlocks front and centre while maximising cycle time. Once we agree on the architecture, I’ll rely on you for ladder (or structured-text) programming, selection of field I/O, panel layout guidance, and all supporting wiring diagrams. If you’re comfortable integrating HMIs or tying the PLC into our existing SCADA via Modbus or EtherNet/IP, even better—the goal is a seamless...

I have an open-hardware setup that links a meshcore nRF52840 repeater to a Raspberry Pi, all powered by a 5 W solar panel and small battery pack. The Pi should stay asleep until the repeater’s heartbeat stops, then wake, push the latest meshcore firmware, and put the radio back online. Before I fabricate anything, I need an experienced hardware designer to go over the schematic and improve it, with special attention to two areas that matter most to me: • Mainboard layout – it must be tidy, electrically sound, and robust enough for harsh, remote installs. • Clock timing around the 4060 IC – the current RC network drifts; please replace it with a resonator or another stable solution and verify the timing math.

I need a batch of custom cables built from scratch, each terminated neatly with the appropriate connectors on both ends. The line will carry a small DC voltage while also handling standard-speed data, so clean signal integrity and reliable power delivery are equally important. You will cut, strip, crimp or solder as required, apply heat-shrink for strain relief, and verify every lead with continuity and load testing before packing. Consistency across the whole order matters more than sheer speed; I’d rather wait an extra day than troubleshoot a cold joint later. Please have your own basic tooling—quality crimpers, multimeter, and, if possible, a simple jig for repeatable length control. When you reply, tell me: • The connector families you keep in stock or can source qu...

I need a compact piece of software that will run a closed-loop control algorithm for an AC motor, using a Hall effect sensor as the sole feedback device. The firmware will sit on a microcontroller that is already wired to the motor driver stage; what’s missing is the logic that reads the Hall pulses, calculates speed and position error in real time, and then updates the drive signals so the shaft tracks a commanded RPM with tight accuracy.
