Circuit Diagrams for 5V Melexis Sensor

On the 4th of February, Public Lab and RISD's Digital+Media Department hosted a Thermal Flashlight Workshop. The workshop went great! All of the students managed to make a Thermal Flashlight in 3 hours, many of them had little to no electronics experience. This is particularly exciting as during the workshop we realized we had ordered 5 Volt Melexis sensors rather than 3 Volt sensor we had developed the circuit board. Thankfully, Jeff, Shannon and I were able to figure out a fix on the run. Attached is a circuit diagram for the Thermal Flashlight if you use a 5 Volt sensor rather than a 3 Volt sensor.

This diagram has one small mistake-- the power to the LED is not actually hooked up. Move it across the board divider so it is connected to the LED power pin.


Should look like this, will post drawing later

Corrected 5.5v thermal flashlight circuit


Do you have the code to enter into the Arduino card? I could not find a link to it. (thanks!)


Hey Y'all,

I fixed the picture! Thanks for noticing the problem.

Also I should note that Leif, has designed a circuit board where both the LED and sensor use 5 volts-I'm going to ask him to put together that circuit diagram.


Is there an advantage to using the 5V sensor as opposed to the 3v?


It's really a cool and helpful piece of info. I am glad that you just shared this helpful info with us. Please stay us up to date like this. Thank you for sharing.
