| - | * Am conectat pe breadboard primele componente ale proiectului: placa ATmega328P Xplained Mini, modulul HX711 si display-ul OLED. | + | * Am lipit pe o placa de prototipare buck converterul si driverele ca sa aibe gnd si vcc comun de la baterie. |
| - | * Modulul HX711 este legat la load cell si la microcontroller prin pinii DAT si CLK, pentru citirea greutatii. | + | * Am lipit pini pe o placa de prototipare pe care am bagat-o in placuta pentru a putea lipi in continuare fire. |
| - | * Display-ul OLED este conectat prin I2C, pe pinii SDA si SCL, si a fost testat cu un mesaj simplu pe ecran. | + | * Am terminat de lipit tot ce era acolo dupa aproximativ 30 ore oneste de munca. |
| - | * In aceasta etapa am verificat separat ca partea de cantarire comunica prin UART si ca display-ul porneste corect. | + | * Am reusit sa ansamblez drona si sa cuprind tot inauntrul ei. |
| - | {{:pm:prj2026:atoader:monitor_hidratare_jurnal_1.jpeg?500|}} | + | * Momentan am reusit sa setez elicele in sensurile bune, deci se ridica de la sol, dar nu pentru mult timp, trebuie reglata software mult. |
