    Simple PCB layout S'est terminé left

    I want to use an Arduino Nano Rev 3.3 to control some external components, so I want to get someone to make a custom "shield" to connect those peripherals to the Nano. I've sketched out a schematic by hand, but don't have experience of laying out PCBs.. and not enough time right now to learn and do it myself. The Arduino will be - communicating to a Windows PC via the USB serial connection - communicating with another 3.3V Serial device (so we'll be using the Software Serial Library for the Arduino) - controlling 2 MOSFETs using 2 digital output pins from the Arduino - controlling H bridge (TB67H451FNG,EL) using 2 more digital output pins from the Arduino The PCB will need set of through holes with solder pads on so I can at...

    Hello, I am looking for some...function that will transform a 300x400 pixel grayscale image png to an array of hexadecimal values ​​in a format suitable for display on a Waveshare e-ink display. Looking at the page of the brand of the screen (Waveshare), after transforming each pixel into its hexadecimal format, it then applies an MSB compression. Going from 120,000 hex values ​​(300x400) to 7500. I already have the function in arduino. I just need the function in python that transforms the image. I am attaching a .cpp file containing the list, to use as an example. It is the one that comes by default in the demo screen.

If significant heat is expected to be generated and require dissipation, this should be noted, but hopefully this will not be a concern as low electrical consumption is a design requirement. 8. Anticipated height with enclosure should be less than 1cm, ideally; up to 1.5cm is OK. 9. The "on" signal should be sufficient to control a MOSFET relay, preferably 5V. One idea for the pressure sensor is to use a material such as Velostat or Linqstat that reduces resistance under pressure. However, I need you to design the circuit for it. The circuit should minimize battery consumption while also obtaining a strong enough signal from the mat to minimize false positives due to stray voltage from passing mobile phones, WiFi and mobile antennas, or a standard U.S. 120...

    As the project title suggests, I require the upgrade of an existing arduino code. The desired updates to the code require modification rather than complete replacement. No additional materials are needed, however the updates will need to be tested extensively before being finalized. The desired outcome is to have the code updated and properly assembled with the right materials resulting in a good result. The necessary full testing must be done to guarantee the desired result. I think it's necessary to check the algorithm for the result of remaining life. that's it HERE the base project to understand : i re made this project with somes upgrades.

    hi I wrote a programming code to control three pressure sensors with a Arduino Mega. I have 5 modi with different units like (mmhg,mbar ..) and 5 switches. I want to turn on each modi when the depending switch is flipped. So I put them in a aray. The idea being that the code in this example reads the voltage on a switch pin and determines whether that voltage is above or below a threshold. > If the voltage is above the threshold, the pin is turned on (1) and if the voltage is below the threshold, the pin is turned off (0). > The code will check the voltage on each pin of the switch and if it is greater than 3.0 volts, then that pin will be set to 1 (on) state. > If the voltage is less than 3.0 volts, then that pin will be set to 0 (off) state.
