Hello, I am an Electrical and Electronics Engineer and I completed my master's degree.
I designed many electronic circuits and I have academic publications on this subject. You can also see this from my portfolio.
Thanks to the electronic circuit design programs I can use, I can design and test the circuit.
I can make the circuit that can be carried easily in the features and dimensions you want. I think it would be better to use a microcontroller for timers.
I always guarantee free support if there is any problem when the project is over.
We can proceed more easily by speaking.
The programs I use regularly:
>> Matlab / Simulink, Python, C #, Arduino,
>> Altium Designer, Proteus,
>> Mutisim, LTSpice, LabVIEW, SIMPLIS, Tanner Tools, TINA-TI,
>> SolidWorks, DesignSpark
Thanks :)
