Necesitamos un programador de arduino para realizar una PCB para calibrador de airea medir presiones y configurar botones.

Hello, I'm looking for an experienced Freelancer to assist with a straightforward yet technically challenging project. The task involves developing a program for Printed Circuit Board (PCB) detection, alignment checking, and coordinate extraction. The program needs to cater to two PCB sizes: 24 x 18 and 12 x 9. On initiating the program, it should request the user to upload an 8-bit unsigned image of the PCB. Upon uploading, the program will facilitate two image displays: one that showcases the original upload and another presenting the processed image - the results of PCB detection and alignment. Key tasks that the program should execute are: Identify the rectangular shape or the edges of the PCB. Assess the PCB's centering and alignment. Render the x, y coordinates o...

I require a circuit schematic design and PCB layout for a solid state relay. The design needs to adhere to the following requirements: Voltage range of 24V-->220VAC Current: 40A Interface: The design will interface with a microcontroller pin. Load: The design is for highly inductive loads Switching type: Random (Not zero-crossing) Protection: The device needs protection against transient voltage spikes with a suitable snubber and protection circuit PCB size: maximum 80x60mm (Preferably smaller) The design should allow for the TRIAC IC (For example) T4050-6PF to be directly mounted on a heatsink on the bottom of the PCB. (The PCB should have a cut-out to allow for this)

Design a circuit to measure the voltage amplitude of a 0 to 480 VAC circuit with a 3.3V microcontroller analog input. The off voltage will be 0 VAC, the on voltage will be 120, 208, 240, or 480 VAC. Assume a maximum input of 1.3x or 624 VAC. All power is at a frequency of 60 Hz. This circuit should not adversely influence the VAC circuit being measured, and it should provide a 0 to 3.3 VDC linear output that can be measured by a microcontroller analog input.

After opening, the program should ask for the 8-bit unsigned image to upload. After uploading it will open 2 windows with the original image and the image with the results. To get the result it can detect the rectangular shape or the edge of PCB. Here are the sample image which shows the output we need.

Using LMC6482, detect when external circuit is at 0 or 24 VDC and output 0 or 3.3 VDC (for input to a 3.3V microcontroller). All I need is a simple schematic with the components identified, including values, tolerance, etc. All components must be through hole.

I want to be able to measure an external circuit that is between 0 and 15 VDC (mostly between 10 and 15 VDC) with a 3.3V microcontroller analog input. Hopefully we can use the LMC6482 op-amp again. ;-) I will pay $50 for this project. All I need is a simple schematic with the components identified, including values, tolerance, etc. All components must be through hole.

I am in need of a skilled freelancer to design an amplifier circuit for me.
