 ===== For beginner =====
-  - For the commands (letter signs) which are coming through RS-232 interface from a computer are being waited. Command “R” lights green LED, “K” lights yellow LED and “P” red LED. “R” is switching all LED-s off.
+  - For the commands (letter signs) which are coming through RS-232 interface from a computer are being waited. Command “R” lights green LED, “K” lights yellow LED and “P” red LED. “R” is switching all LEDs off.
   - If a button is pressed, the name of the corresponding button (S1, S2, S3) is received in the computer through the RS-232 interface.
 ===== For advanced =====
-  - Kahe kontrolleri RS-232 vaheline suhtlus. Nupule vajutades saadab kontroller nupu numbri. Numbri saabumisel muudetakse vastava LED-i olekut. '1' -> roheline, '2' -> kollane, '3' -> punane. Vajab kahte kontrolleri komplekti, kuid tarkvara on mõlemas kontrolleris identne.
+  - The communication between two RS-232 controllers. If a button is pressed, the controller transmits to the controller the number of the button. When the number is received the status of a corresponding LED is changed. '1' → green, '2' → yellow, '3' → red. Requires two sets of controllers, but the software is identical for both controllers.
-  - Teha "teletype"-seade, mis võimaldab kahe kontrolleri vahel RS-232 liidese kaudu vahetada tekstisõnumeid. Sõnumite kuvamiseks kasutada LCD ekraani, mille esimesel real on näha oma sisestatavat sõnumit, teisel viimane vastuvõetud sõnum. Sõnumi sisestamiseks võib kasutada potentsiomeetrit ja/või nuppe.
+  - Make a  “teletype” – device, which allows changing text messages between two controllers through RS-232 interface. Use LCD for displaying the messages. On the first row must be seen inserted message and on the second the last received message. For inserting the message a potentiometer and/or buttons may be used.
-====== Kordamisküsimused ======
+====== Questions ======
-  - Kirjelda UART-i paketti.
+  - Describe the UART package.
-  - Mis asi on boodikiirus?
+  - What is the baud rate?
-  - Mis vahe on täis- ja poolduplekssidel?
+  - What is the difference between full- and half duplexes.
-  - Leia vähemalt 5 erinevat andurit, mis kasutavad jadaliidest.
+  - Find at least 5 different sensors which are using serial interface.
-  - Mis vahe on UART ja USART liidestel? Kumb on kiirem?
+  - What is the difference between UART and USART interfaces? Which is faster?
-  - Kuidas töötab SPI liides?
+  - How is the SPI interface working?
-  - Nimeta liideseid, mis võimaldavad ühele siinile ühendada vähemalt 100 seadet.
+  - Name interfaces, which enable connecting at least 100 devices to a single bus.
-  - Loetle erinevaid topoloogiaid ja selgita nende erinevusi.
+  - Name different topologies and explain their differences.
-  - Mis pingenivool toimivad RS-232 ja UART ühendused?
+  - On what voltage level are RS-232 and UART connections happening?
-  - Kui palju aega kulub 1 MiB edastamiseks boodikiirusel 9600 bps, kui andmebitte on 8, stoppbitte 1 ja paarsuse kontroll puudub?
+  - How long time takes to transmit 1 MiB at the baud rate of 9600 bps, when there is 8 data-bits, 1 stop-bit and not parity control?
