    It's a device that counts objects that passes by. Pressing the start button on the 4x4 keypad will start the counting of objects. Every time the interrupt is triggered(falling edge), the count should increase by one and be displayed on a 5-digit seven-segment display. The code is written by another Freelancer who is not available at the moment, and I need minor changes in the code. Point no. 1: I am using the Up and Down buttons of the 4x4 keypad to set the values by incrementing and decrementing by 1. But if I don't release the button quickly, the count is sometimes incremented 3 to 4 times. I want the code to be changed so that when the button press is detected, it will increment by only 1 value and wait for the pressed button to release. Point no. 2: The value which is set...

    We have some pcb water heater controllers we wish to QC test. We want to build a rig that can run through a standard set of inputs repeatedly to simulate actual usage much faster than happens in normal operation. There is a document attached with more detail. Please quote for the development labour time only, we will pay for the hardware components (or potentially build it ourselves under your guidance). We can send parts and collect a solution item via Fedex at our cost but would prefer a freelancer country that is low cost/easy to do this (eg without undue customs difficulties). If there are any questions to clarify please ask.

    The pcb design that i made has an small error and i need someone to help me figure out the issue. Its a combination of Arduino Nano MCP328P + MCP2515 CANBUS board but in a smaller size with lots of extra arduino nano stuff removed as i will not be needing it. MCP328P chip and FDTI chip do communicate with PC and all digital/analog in/outs work quite well so no issues there, however the MCP2515 part is not able to receive nor send CANBUS messages so i am guessing within this simple pcb design i made an error that i cannot figure what is.

    We are a company that sells a 'CNC' Machines. The aim of the project is to set up an online SERVER that controls all our machines through a SCADA connection and find the required electronic devices. This server will: 1. receive the machine user job request (HMI); 2. calculate the job to be done (already coded in python and finished); 3. send the G-Code commands to the machine in order to achieve the job requested. At the end of the project, the SERVER is the centralized head of all machines and the machines itself do not require a PC or software, just a IoT connection to send job requests and receive working commands. Thanks, Tomas
