# Hardware

Here you'll find some links and suggestions on the hardware you should use for your own Amsel bot. Unfortunately we can't provide a predefined package. Also we can't guarantee the perfect fitting of suggested parts due to changes in the factorying. When you try using it in an university environment or course, we recommend to buy the same parts as your fellow students or try to order together. That'll make it cheaper and the debugging is easier when done in a group.

# Microcontroller board

As a board we decided to go with the cheap ESP8266 NodeMCU. It already provides some keyfeatures like onboard wifi and is widely used in all areas of application.

3x ESP8266 NodeMCU Lolin WiFi V3 module	~ € 12,00
1x ESP8266 NodeMCU Lolin WiFi V2 module	~ € 7,00

# Motor driver board

For controlling the motors we chose a L298N dual h bridge. we discoverd that this product won't work with an ESP32 board.

5x L298N dual h bridge	~ € 16,00
1x L298N dual h bridge	~ € 6,00

# OLED display

For showing information on the robot we chose a economical 0.96" OLED I2C display. The size can also increase in the future years when bigger OLED displays get cheaper.

3x 128x64 pixel 0.96 inch OLED I2C display	~ € 13,00
1x 128x64 pixel 0.96 inch OLED I2C display	~ € 6,50

# Ultrasonic sensor

As a cheap possibility of measuring distance we chose a ultrasonic sensor, which is able to detects a minimal step of 0.3 cm.

5x ultrasonic module HC-SR04	~ € 10,00
3x ultrasonic module HC-SR04	~ € 7,00

# DC motors

For the motors we used a cheap model wich is easily testable on 3V and performs with voltages up to 6V.

4x 3-6V DC gearwheel motor	~ € 19,00
2x 3-6V DC gearwheel motor	~ € 10,00

# Jumper wires

For connectiong all the parts, jumper wires are the most valuable way.

40x Jumper Wire 20cm FF MF MM	~ € 7,00
40x Jumper Wire 20cm MF	~ € 4,00

# Bread board

Consider using a breadboard for quick and easy tinkering

3X 400 Pin Breadboard 4 Stromschienen	~ € 7,00
