Hi Jacket,
That is just a Seeed Studio Screw Shield.
Results did not change whether I connect the Tick Tock Shield direct to the Seeeduino or with the screw shield in the middle.
I use the screw shield so I can put an alligator clip at the GND terminal.
I know the buttons, buzzer, LEDs, thermistor, LDR sensor and 7 segment display work.
Is it possible the common cathrode 7 segment display in this kit is not compatible with the TM1636 IC?
