in java please and arduino view needed

Question 1: [ 30 pts] Our goal in this project is to use a seven segment display controlled by two buttons BUTTON1 and BUTTON2. Pressing BUTTON1 turns on b and c, which corresponds to the number 1. Pressing BUTTON2 turns on a, b, c, e, f and g, which corresponds to the letter A. Question 2: [ 30 pts] Project #38: Building an Analog Thermometer Using our servo and the TMP36 temperature sensor from earlier chapters, we'll build an analog thermometer. We'll measure the temperature and then convert this measurement to an angle between 0 and 180 degrees to indicate a temperature between 0 and 30 degrees Celsius. The servo will rotate to the angle that matches the current temperature. The Hardware The required hardware is minimal: One TMP36 temperature sensor One breadboard . One small servo Various connecting wires Arduino and USB cable Question 3: [ 40 pts) Our objective is to detect Tank Bot collision with an Ultrasonic Distance Sensor. We check for distances of less than 10 cm, which will set the angle of servo to 180
