I want to make an EFIS - this is a service used by pilots at an airfield. The device is normally in listen mode - when it gets three clicks about 1 second apart, it goes into transmit mode. I would guess that pulling a GPIO pin low would work for that. It then reads out a brief text file with the weather conditions. I can handle the preparation of that. The Pi is interfaced to a radio as an inpu...

I need to comunicate up to 32 nodes (esp32) to a single station / root (Esp32, Rasp whatever you recommed me) I have preference to use esp32 features (esp now - esp mesh - lr mode) but if you have an alternative solution (with aditional hardware) will be accepted as well Please, don't put commercial or generic text in the proposal I will not reply, tell me I little about your possible solu...

I have a timer that works well, but I would like a few improvements, the main issue is when setting an alarm that straddles across 12am (midnight) the output will switch off early, for example if I set an alarm for 10pm to run for 3hrs the output will only be high for 2hrs and then go low, second I would like the interface / menu to be altered, it is currently set up to display 7 outputs (A-G) I w...

i am looking to have a new cnc shield designed for a arduino uno that will have a dedicated header for a Pololu style driver with the option to plug in a cable for step direction gnd and enable the pcb must also have headers for the power input and the motor outputs the end design should be a single shield for a arduino that can have 2 tb6600 drivers screwed directly onto the board to feed power a...

We are seeking cooperation with experienced Electronics Engineers with experience in Digital Signal Processing to build a prototype of an Android OS-based Audio/Loudspeaker Measurement App with an automatic Equalizer.

I need somebody with tools and skills to perform some basic USB and Ethernet connection soldering directly on the board. This project is for LONDON ONLY. I will need to meet you in person to give you the boards that needs to be done.

Project at Design Innovation Centre, New Delhi. Requirement: Circuit diagram for arduino controlled prototype of a thermal cycle, in combination with a frequency detector to guage and plot frequency (visible light spectrum) versus cycle number.

I have an embedded program for a USB mouse. One of the peripheral chips is not available anymore, but there is an almost identical chip. The only difference is the product number, which is 0x23 instead of 0x32. I just have to change this one number. It doesn't even have to be recompiled, although it would be better as there could be other modifications. I have all the files except the very la...

I want to make a vending machine controller based on Raspberry Pi and Arduino. It will use pulse based multi-coin acceptor and bill validator. 20x4 I2C LCD and Matrix keypad will be the GUI. I will provide sources from an open source VMC based on Orange Pi Zero for guide.

The application should measure weights up to 200kg, through 4 load cells of 50kg connected to the HX711 module. The code must run on NodeMCU. Attached photos with mounted scale. The scale should start by informing the current weight on the scale. With known initial weight, the weight of the cylinder informed by the user must be subtracted. The IDE Arduino Console should display: 1. Current wei...

Hello I have a Arduino MEGA 2560, and NODE MCU, I need them to talk to eachother, simple bridging code, plus tell me how to wire it all together. I already have 2 separate codes. 1 for NODEMCU and one for the mega. Many Thanks

I have completed the main section of Python code, I need help with building a web interface that displays 2 live updating graphs (from the sensor data my program obtains), and also displays 2 online clocks, which I have already coded in python (one is standard time, the other varies according to the sensor data). Graph 1 is frequency varying with time. graph 2 shows how the time difference between...
