    There’s some things I didn’t specify in this drawing. The esp8266 has 15 pins on both sides, The lcd adapter has 4 pins to the left and 16 pins at the bottom. Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them. I’ll just need it printed as for which hole is which. Phone number is 7868779321

    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.

    I need help with design of a device which can take DC (variable voltage as input from 12-60v) and convert that into an AC 110 volt 60 Hz (also 220 volt 50 Hz) and such device should be able to sense voltage and frequency of the grid , where we are trying to feed , and based on that, it can synchronize frequency and voltage. And then it can feed power to the grid, but say from usual household plug so that it becomes portable device for say uto 1000 Watt portable solar power generators, wind generator. If output voltage sensing is difficult then probably 2 models - 110volt 60 Hertz and 220volt 50 Hertz. Also need a prototype shipped to me to US, along with all the schematics, drawings, designs.

    This project is based on ESP8285 microcontrollers and programming should be done in Visual Studio Code (PlatformIO) Background: This is supposed to be a monitoring system. It involves detecting sensor values at multiple locations (at least 25, with more to be added, on demand). Each sensor location is connected to an ESP8285 wifi board on UART1 (soft serial). All of the 25 individual wifi modules will connect to a central hub - which is another ESP8285 module. This central hub will be connected to a cloud server through a broadband router. It will send the data of all the 25 sensors to the cloud server. The cloud server will also reply back some data which needs to be transmitted back to the 25 sensor modules. Based on this data, the individual 25 sensors will perform some action, like ...

    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. I have very good coding skills and some basic electronics knowledge so I will be able to provide feedback and help with anything...
