    I need a control system for the liquid level in a tank. Use two sensors (wires); one at the bottom and one at the top. Once the liquid touches the two sensors and stays like that for 5 seconds, the Arduino card should be able to "read" it and turn a 5V pump on. And the other way around for turning off the pump. Potentially usable additaments are welcome. Now, think about this 1-tank but for 8 independent tanks and assemble it the simplest and most elegant way you can. I will require the circuit diagram, the program to feed into Arduino (with comments for mortals), and the list of items to buy on amazon.

    Hello, I need an Arduino Nano program to run a nema17 stepper motor with a 8825 driver. It must be controlled by a potentiometer in A0. The motor must be able to turn in both directions with a stop range configurable on the potentiometer between the two directions. There must be no jerks when starting the motor and the acceleration must be progressive until the desired speed. The direction of the motor and D8 and the pulses D9. D7 must be activated when the motor is stopped. The maximum speed, the curve of (acceleration, deceleration) must be configurable. I have two code examples to show what I need. The first one illustrates the good configuration with a good control but the engine starts without acceleration with noisy or disturbed signal. The second code illustrat...

The project should include the code for the transmitter and the one for the receiver and the stl file for the 3D printing of the trasmetter and the receiver containers. The transmitter container should be as small as possible, considering it needs to support a small battery and transmit to long distance with the best quality as possible. Mini usb rechargeable and mini solar panel included to recharge. The receiver should be as thin as possible and it should have a thin battery both transmitter and receiver batteries sh...

FULL PROJECT DETAILS ARE IN THE PDFs. Do not bid if you have not read this. Payment is for the full scripts and verifying that it functions with the hardware. Therefore, some light troubleshooting with hardware is expected to verify your code is working properly. Lastly, I will NOT INCREASE YOUR PAY if you do not estimate the time investment correctly. If you ask, the project will terminate and be disputed (have seen this too much on here lately and it is frustrating).

    Build a new PlatformIO/Arduino project in C++ using the Seed XIAO sensor platform. Using the available public libraries create a bluetooth peripheral for the PDM microphone, pair the microphone and stream the microphone audio to the host. Using the available public libraries create a bluetooth peripheral for a MS5837 pressure sensor pair and and publish the calibrated pressure and temperature to the host on an interval set by a pushed value from the host. Detect when the XIAO has been moved using the IMU and wake the core from deep sleep on movement. Detect when the XIAO has has not moved for a time and put the XIAO to sleep. Based on the comments received we are pulling this post and will repost with a modified SOW and requirement.

    I need help creating a custom DIY bark repellent device. It can be based on Arduino, Raspberry or pure electronics - Raspberry and Arduino being the best as they can be easily updated or programmed. Anything I can find on the market are small toys without the much required power. It has to use larger loudspeakers - not the tiny kind you see in any bark repellent It has to allow change of frequency (as in adjusting for a specific dog/animal). From what I understood it has to emit ultrasonics around 20kHz-25Khz (in case of dogs) so it is not a such complicated device but I need someone to think about all these aspects and compatibility of the electronic pieces.

You do not need to have any experience to work with me on this project because I would rather work with a person who is inexperienced but intelligent, rather than a person who is experienced, but not very intelligent. You will need to prove to me that you are a very intelligent person. Normally, you must work five days each week for one hour each day.

    Hello, I am currently working on a heating control project that uses an Arduino board and a motor-controlled valve to regulate the flow of hot water from a primary circuit to a secondary circuit. The primary circuit is connected to a source of hot water (fernwärme/district heating) that maintains a temperature between 60 and 120 degrees, and a permanent pump that can not be controlled or regulated. The secondary circuit is also connected to a constant-speed pump and the goal is to maintain a temperature of about 40 degrees. I have implemented a basic control logic using switch cases and if-else statements, but I am having trouble getting the system to accurately regulate the temperature of the secondary circuit. I have read that using a PID controller can help improve the perf...
