    ...to read the signal, display it on a small screen, and allow for a user selectable delay to close a circuit. The trigger will actuate a raspberry pi. I am looking for someone to design and build me 2 or 3 physical triggers. The objective is to create an electronic trigger that is actuated via LTC timecode input. Input Signal: LTC Timecode via 3.5mm audio Jack (the sound is mono, need to check the channel) LTC is a manchester encoded signal, wikipedia has information about it. Each frame end is terminated with 12 highs. I need a small display to show the decoded timecode. I need to be able to add a user defined delay to the triggering mechanism. The triggering needs to close a circuit to actuate a raspberry pi. I also need a mechanism to send the timecode ...

The pellet boiler stove has an integral pump which activates when the water in the boiler reaches 70c.

    My project consists in a circuit board which is responsible for communicate with the internet and triggering 4 electronic locks of 3V 1.5a using relays. Due to high inductance generated by the electronic locks, it is necessary that the circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs. The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours. This circuit will be activated when the site is without power. To connect the ESP32 to the internet, a 4G modem is connected to the board. The board must have a female USB connector to power the 4G modem. The female USB connector must have a circuit capable of having its power interrupted by a command sent by an ESP32 I/O p...

    Hi all. Using the Arduino IDE, I need to use a microchip SAM L21 MCU in my circuit, with a Watchdog feature. Unfortunately , the watchdog setup is well documented on the SAMD21 chip (lot of tutorials and sample code online), but not on the SAML21, which differs on the internal clock used (if I understood correctly). So the project is the delivery of a functional watchdog code for a SAML21 in arduino, including any necessary original or modified libraries (a good library example of WDT library for the SAMD21 is ) You don't need to have access to a SAML21 hardware, just to provide a functional code that compiles with no error. Technical info : the Arduino board manager uses the following board library :

The simulation must contain one complete cycle of the counter and test all functions. It must show that the synchronous load really is synchronous and that the clear has precedence over load, which in turn has precedence over count enable. -Write a VHDL file for a two-digit BCD counter with active-LOW asynchronous clear, active- HIGH synchronous load, and an active-HIGH count enable. -The counter must count up from 00 to 09, then 10 to 19, and so on until it reaches 99.
