i will be using some coating materials.u were talking about that cross only know.even i too got the same feeling then some of my friends told me that we can use the wire with plastic coating.so that problem wont come...
yea i am using insulated wire..OK, so you are using insulated wire links.?
Because you are switching LED's I would increase the value of C3 capacitor, what is its present value.?
Also add a 100nF decoupling capacitor close to the MCU on its power pins. pins 10 and 11
yea i am using insulated wire..
value of c3 now is 100uf.should i change it?
i have put a capacitor between 10 and 11 of mcu.
i am not familier with max7219.is there anything else i will have to include on the max7219 part?please check that part and let me know...thank you...
