I am seeking an experienced Arduino professional who is able to provide assistance with setting up a Nano model. This job requires someone who is familiar with the different components and their specifications in order to ensure proper setup. I am not in any particular rush to have this task completed and am looking to hire someone with the right knowledge and dedication to get the job done properly. If you feel your Arduino skills are up to the task and you have the necessary time to allocate to helping me out, please reach out.

We are looking for someone with experience in building transformer base 3 phase inverter. We are having issues where mosfets are burning. We built a buffer board using CD4011 ic to split the driver signal into 6 channels which is 3 for the high side and 3 for the low side. Then we built a transistor board and an optocoupler board that is used to feed the signal to the driver board which was designed using IR2110 ICs. This driver board is what should drive the emulator board (the mosfets) which receives the battery input and then drives the transformer. Currently the mosfets keeps getting hot and burning

AMP BRIDGE . Its Home Flex 50-amp smart charger is similar in operation to its public chargers so there is no learning curve. It can be hardwired into a 240-volt circuit (typically the home’s drier circuit) or an existing 240-volt outlet. The 23-foot cable allows for more installation locations in your garage and the whole charging unit has a sleek design Sometimes you don’t need smart-charging capabilities. Instead, you might need a durable outdoor charger that can withstand tough weather conditions. AMPUSHER is ideal for home EV charging, as well as electric lawn/farm equipment, which is a growing market. There’s no app to this one, just a rugged 40-amp charger. This unit can be hardwired or plugged into an existing 240-volt outlet and the power output is adjustable

Make schematic of a project along with its PCB layout.

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar

Design an induction heater driver circuit (including schematic) powered directly from 230VAC (without needing a separate DC power supply), which can drive high frequency AC (>10 MHz) through a ~12 mH work coil to heat its core as quickly as possible (red hot in <5 seconds at max power). * Max power shall be limited to 3kW, to limit the current at power source to 15Amps. * Inductance of the work coil will remain constant during operation. * Circuit shall only include ordinary components available OTS (i.e. no specialized/custom components). * Circuit shall be able to operate continuously for at least 600 seconds at max power. It's OK if the components need ordinary active cooling. i.e. Should not require specialized cooling like liquid nitrogen. * Bonus feature would be if the c...

We are in the end phase of developing several new tabletop products for the professional food industry. We want to create a great user experience for the interface. The first project would be to take over the software from one of our R&D partners - he makes the PCB prototypes and some of the mechanical solutions. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the product. It works, but it needs a talented UX developer to create a far more intuitive and more attractive interface. We would also like to add a language pack. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the produ...
