In todays task we learned how to make a lander test. which shows us hwo to test a lean mixture and a right mixture.

first thing we did was to install the follow components on the O2 sensor PCB board.

The equipment we used to create this was resistors , rectifier diodes, zener diode , capacitors, 3 LED lights , (green , red , yellow)  ,  jumper wires  , (Red, Black, Green) Ic chip LM324,

Then we soldered the the equipments on PCB board.

In conclusion
this gave us an idea of how a lander tester works. its shows the rich mixuter and the lean mixture. when its reving high it turns red that means its a rich mixture. the yellow LED is a signle going between the Red Led and the Green LED. and the green LED it shows its a lean mixture when the car is at a normal revs.
