I’ve searched, but maybe my search terms failed me, so I’m asking:
I’m using a MEGA2560 Arduino with the Sainsmart TFT Sheild to run the 2.8" 240x320 TFT display.
Works like a charm.
However, I plan on using the display to track moisture and humidity, so I now want to connect a DHT22 sensor somewhere onto the Arduino.
As it turns out there’s only the ONE 3.3v pin, and it’s directly injected into the shield that the TFT is using.
How have you hiveminders dealt with this “out of pins” situation?
I’m thinking I could totally hack it, by trying to solder on a ‘breakout feed’ to the side of the 3.3v pin, and feed a small series of pins on a protoboard (with another feed for gnd going back to the Arduino as well)
I can’t be the first person to hit this snag – finding the Mega can only do the ONE thing if using the TFT Shield, but I’m feeling the above is quite the kludge.
Is there a better solution?
