@ -31,7 +31,29 @@ Now it's time to rotate the hand to the desired position. Lets assume, we want t
hand.setRotation(170); //set the rotation to 170 degrees hand.setRotation(170); //set the rotation to 170 degrees
hand.fill(&tft,120,160-pivy,TFT_GREY); //draw an fill the hand. hand.fill(&tft,120,160-pivy,TFT_GREY); //draw an fill the hand.

Repeating the steps above for the minutes and seconds hand and we are ready. Repeating the steps above for the minutes and seconds hand and we are ready. And here is the complete code for drawing the analog clock:
```javascript
TFTShape dot=TFTShape::buildNgon(8,6);
TFTShape grid5minutes=TFTShape::buildNgon(12,100);
//clock-face
grid5minutes.fill(&tft2,120,160,dot,TFT_GREY);
int pivy=35;
//hour-hand
TFTShape hand=TFTShape::buildNgon(5,60);
hand.setScale(.08,.8);
hand.setPivot(0,pivy);
hand.setRotation(170);
hand.fill(&tft2,120,160-pivy,TFT_GREY);
//minutes-hand
hand.setScale(.08,1); hand.setRotation(240);
hand.fill(&tft2,120,160-pivy,TFT_LIGHTGREY);
//seconds-hand
hand.setScale(.03,1); hand.setRotation(30);
hand.fill(&tft2,120,160-pivy,TFT_RED);
