Hi, My IC is Pic16f676. See My Attached Picture for Details.

1. Computer or pc have excel/CSV data. 2. Raspberry pi connected to PC using LAN How to raspberry pi can read excel data in PC and post to telegram every 2 menute.

1. With an external trigger it should record video @720P or take images as per user configuration 2. After a predefined time of video the controller will go to sleep mode for power saving. 3. Controller should wake up within 0.5 seconds of interrupt. 4. Choose any cheap controller/ processor of your choice. Please explain in the proposal itself how will you do it.

I am looking to have a small mini microphone built with bluetooth capabilities powered by a lithium ion battery. I would like one built along with a full build order.

I am looking for someone to design a simple high side PWM circuit. This will be running at 12-15vdc and could theoretically have a load of 15A max. It can't be low side because the negative terminal of my PWM controlled device is grounded to the frame. I prefer Kicad, or Fritzing as those two are easiest for me to customize my board layout in. If you can make the circuit entirely using digike...

I need a sample code in Arduino for STM32F103 uC to bring the uC to sleep mode and wake it up by external interrupt and internal RTC alarm. the power consumption of uC should not be more than 10uA in sleep condition. when uC wakes up it continues from the point it stopped. There is no ADC on this project. we need to access 2 serial ports, I2C bus and few input/ output when device wakes up. Maxim...

Require to programming this microcontroller from scratch. All hardware required will be informed by you

This is about a motorcycle project. I want to control 5v signals (max 4 of them). I need to calculate the HIGH ones. When the calculation meets a specific limit number and a switch is pressed I want to interrupt the signal. This is the basic idea, it will be a bit more complex in the end but I don't want to make the project public. I also want to set the limit through a smartphone applicatio...

A simple clockdivider code but if you need more details message me. I am a student so I would give 10 dollars for this. Need it in 2 days

I am using arduino mega 2560. I have a master arduino and a slave (display). They are communicating over SPI protocol where display expects the master to send data at 50 KHz i.e. the SCK pin from master to slave should operate at 50 KHz instead of buit in 16 MHz clock. Is there a method to reduce the clock frequency ? Altrernative method (no preferred) would be to generate a 50 KHz signal using ti...

In this project, we are collecting the data from a sensor and converting analogue data into digital using an ADC which is interfaced to a processor using SPI interface. The requirement is to collect the same number of data points every second which is equally spaced with minimal noise from sensor and ADC. Information about the ​sensor, ADC and micro-processor will be discussed in person.

I am looking for someone that can do a raspberry pi project for a tool control project I am proposing. What I am looking for is when a hall effect sensor is tripped it will light up a led and then display the tool name on a screen via HDMI. Then when the sensor is un tripped the led will turn off and the tool name will be removed from the screen. I will need to control a minimum 256 sensors. I...

I need someone to help me with a project that I am working on which involves an arduino that is connected to 6 push buttons as inputs and 6 motors as outputs. The theory is pretty simple, when one presses a particular button it should trigger a certain - or several - motors to be on for a short amount of time, and then turn off. I can give more details to whomever takes this up.
