I have a DHT11 sensor and a 16x2 LCD screen which both need ground/+5v.
The breadboard I see is a series of vertical strips, separated in the middle.
If I use one strip for the +v with the 5v power from the arduino on the end of the strip, and the DHT11 and LCD plugged into the same strip, will the LCD and DHT affect each others voltages? (ie series).
Like I said I am using one strip for +v and one for gnd, everything that needs either of those is just plugged into that strip and connected to the arduino. If I need a resistor as for the LCD, I connect it either side of the breadboard seperator, so that the current connects the strips through the resistor.
E.G for the LCD pin #15 'A' (I think its the backlight), is connected to a bottom strip, then a resistor leads to the top strip, which has the LCD pin #2 'VDD', the DHT pin #1 +v, and a wire from the 5v power on the arduino connected (in that order).
So would the resistor used for the backlight of the LCD affect the voltage of the DHT and vica versa? The +v from the LCD VDD port also contains a resistor joining two strips before it is connected to the "+v top strip".
Please tell me if this is wrong and if I should be using some kind of parallel connection, and how? :S
