Hi all,
I was trying out some projects with arduino . I was curious to know the changes in the readings that an analog input will show when it is left free than when touched (through a wire) . So I tried it out and when I touched it nothing happened . But when I touched the wall while holding the input pin ,I felt a electric shock which wasn't too high but was enough to make my hand fell the discomfort for few minutes. I didn't know how I felt that . I was programming my arduino in my PC .So I thought that it must be due to the smps power supply which usually happens when we touch a smps supply. My question is how did I fell that shock in an input pin? In my case it was A0 pin on the arduino which is the analog input.
Please help me understand what really happened here .
Thanks in advance .
