Description
A device that is used to see the reaction time and the memory score of people in a fun and interactive way.
Motivation
I always liked to use sites like HumanBenchmark to see the differences between me and my friends. We used it in a competitive way and I figured that it would make an interesting project for this subject.
Architecture
Here is the schematic of the project:
Log
Week 5 - 11 May
I bought all necessary components for the project. This involved researching and selecting the appropriate hardware specifications to match the project requirements and placing orders for all components.
Week 12 - 18 May
I focused on building the complete hardware setup of the device. This included:
- Connecting the main Raspberry Pi Pico 2W to the LCD shield using the 8-bit parallel interface
- Setting up the AT24C256 EEPROM module with I2C connections to the main Pico
- Configuring the second Raspberry Pi Pico 2W as a debugger with SWD interface
- Assembling the power distribution system with the breadboard power supply and 12V adapter
By the end of the week, I had a fully assembled hardware prototype ready for the software implementation phase.
Week 19 - 25 May
Hardware
The project uses two Raspberry Pi Pico 2W microcontrollers - one as the main controller and one as a debugger. The display is a 2.4" TFT LCD Shield with ILI9325 controller that provides both visual output and touch input capabilities. For persistent storage, an AT24C256 EEPROM module stores game highscores. The system is powered by a breadboard power supply connected to a 12V adapter, which was chosen to provide sufficient power for the LCD's higher current requirements. All components are connected using jumper wires on a breadboard.
The main Pico 2W is connected to the LCD through an 8-bit parallel interface (D0-D7) plus control signals (RS, WR, RD, CS, RST), while the EEPROM communicates with the Pico via I2C (SDA, SCL). The second Pico 2W is configured as a debugger using the SWD interface, allowing for real-time debugging and program uploading.
