I have a working unit that a freelancer built for me in Aruduino (got a .ino file) and I built with the components list that the freelancer sent and the PCB that he planned (sent it to Seeed to print). It's about 90% tested but I have some issues that are code related that need to be fixed. I have attached the job description of the job of building
We need a small PCB that has a Lithium ion battery Charge circuit that charges a 3.7 volt 180mah battery and also an RF 415 Mhz receiver circuit on one PCB. I would like the PCB to be 30 x 20 mm maximum in size. Is this possible? The board would need a micro USB port and on/off button on board.
...(robotic tank + robotic arm mounted on top). So, my robotic tank (controlled via blueooth) is working perfectly but I am having issues with the robotic arm. I'm a beginner Arduino user and don't have the coding skills to be able to code the robotic arm myself yet. I have the 6 dof robotic arm assembled and I have purchased an Adafruit 16 Channel Servo
I nee...modem quectel M66 that are unsupported. The library needs to receive and send MQTT messages to our MQTT server. Need to work at lest with QOS 2. We have M66 hardware and arduino uno and to get project a probed the fork need to pass the test of this sketch: [login to view URL]
i am in need of someone to finish some prototypes for me. - a pic controlled optical tremolo distortion circuit (pic code all done, just need board layout which is part done, and a good layout to eliminate clock noise) -simple octave up and reverb circuit (layout done, but signal does not pass as should) - a simple two stage distortion circuit (layout done but gain is too large between stages) -a...
To develop firmware for Following PCB (3 types -RTU,DTU,Repeaters). RTU PCB:- It has digital inputs & outputs & it should send data of inputs to remote(DTU- Data monitoring system in MODBUS RTU protocol & it communicates with DTU in wifi network. DTU PCB- It gets information from RTU & transmits the data to PC to which it is connected with ethernet

All 4 loctlocat synchronisation of lights on off 3 press Lt a on rest off 5 press Lt b on rest off 7 press Lt c on rest off 3 sec press lts which was on blink 5 seconds press all off Valid input within 5 second of first press. Keep state same
Hi, I want to develop a lighting sensor using a raspberry pi or arduino. The idea is : we have a LED Light with a PIR sensor on it. we want to have an ambient sensor ( like a BH1715 or similar) on a rasberry pi which will trigger the PIR sensor of the light when the sensor reaches a defined lux level.
...Freelancer • Jobs • Electrical Engineering Requires developing an embedded systems hardware and firmware of Arduino to connect 1 motor, 1 solenoid, 1 LCD, 1 Ultrasound Sensor, 1 Arduino board, and a battery that will measure liquid flow. Arduino board will receive two inputs (battery, ultrasound) and send two ouputs (LCD, Solenoid). All components will
To do a PCB schematic and layout design for a small foot-print PCB board for wireless module. PCB board contains USB, MCU, wireless chipset (IoT wireless chipset), antenna, and a number of connectors. Must have experience with antenna, RF, and USB impedance control, ground isolation and layers, and USIM and other connectors. CAD tool is EAGLE or Altium
I want to create a sensors station with an arduino to get sensors data and send it wireless to a server. I need an arduino expert to code it. This is the initial project but I'm looking for a long time relationship. Please write me by pm for details.
Looking for a simple program so that an Arduino (or RasberryPi) can control an AC motor. The system will need to be able to do the following: * Start and stop the motor * There will be mechanical limit switches that will shutdown the motor when tripped. * Restart the motor after limit switch has been tripped via UI (mobile application, Web UI etc
...data(both XYZ and rotation) to an arduino(Com port). One of the challenges is that the rotation data needs to be in EULER so that gimble lock is avoided. (For examnple the tracker postion needs to be able to rotate more than 360 degrees - if it is rotated 2 times on an axis - the value sent needs to be 720) The arduino needs to recieve this information
