    Arduino stepper project I need a capacitive touch (like TTP223) which, if hold down for 5 seconds, turns the whole device on and off. i also need a screen (EDO E1473AC63) with three buttons designed, a bar to indicate the battery level and a bar to indicate the stepper motor effort. if the buttons are kept pressed, they activate the stepper motor. the engine starts only if the button on the display remains pressed. if the button is released, the motor stops. There are three because they have different acceleration and maximum speed. acceleration and maximum speed must be set from a smartphone that communicates via bluetooth with device. I also need a function that if I press three fast touches on the display with two fingers, the motor moves to the zero position (the zero position...

    Code for arduino needed. I want to the machine to run until ice is ready to drop into container in short. What I want to do is use a sensor (it's just 2 copper pieces like screws) to connect to each other as soon as the ice is thick enough that completes connection to initiate the drop cycle. (contact with ice on sensor should be for 20 seconds incase false reading) After that it should activate a relay that controls the ice drop until it's finished. After ice dropped the sensor disconnects and relay switches off.

    We are looking for a senior firmware developer who can consult us on various aspects of development for BLE application using the NRF52 and other Nordic Semiconductor System-on-Chips (SoCs). The first job on hand (this request) is low power optimization of an existing application, this would require good co-ordination with our developers (remote teams), firmware review, bug fixes, and adaptations to reach the desired power consumption levels. Expert knowledge of low-power schematic design, firmware development and integration is a must. We are looking for individuals and NOT companies (any time zone is okay, but we prefer Central Europe).
